Introduction

This package includes several helper functions for working with knitr and latex. It includes xTab for creating traditional latex tables, lTab for generating Longtable environments, and sTab for generating a Supertabular environment. Additionally, this package contains a knitr_sethooks function. knitr_sethooks serves two purposes. First, it fixes a well-known bug which distorts the "results='asis'" command when used in conjunction with userdifiend commands. Second, it provides a com command (\<\<com=TRUE>>=) which renders the output from knitr as a latex command.

In the examples below, the code is shown as it would be provided in a knitr chunk, with the resultant latex depcited below. If this was an actual latex file, setting results = 'asis' would eliminate the comment markings (which is generally what you would want). Additionally, the examples below show only the basic usages of each function. For a more detailed examination, you should view the vigenttes or the help documentation. To see a complete working example, see the documentation provided inst/example (if you are viewing on github).

Important Notes

xTab

xTab is a function that produces a standard latex table/tabular environment

Basics

Standard xTab table

To produce a latex table, simply pass a matrix or a data.frame to the xTab function.

xTab(cars)
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\

## \hline
## \end{tabular}
## \end{center}
## \end{table}

Labels

## \hline
## \end{tabular}
## \label{tab:mytable}
## \end{center}
## \end{table}

Captions

Place a caption at the top of the table.

xTab(cars, caption.top = 'my table')
## \begin{table}[ht]
## \begin{center}
## \caption{my table}
## \begin{tabular}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

Place a caption at the bottom of the table

xTab(cars, caption.bottom = 'my table')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \caption{my table}
## \end{center}
## \end{table}

Booktabs

Setting booktabs = TRUE sets the defaults of the toprule, midrule, and bottomrule arguments to \toprule, \midrule, and \bottomrule respectively. When using booktabs rules, regardless of whether you set booktabs = TRUE or set them individually, make sure to include \usepackage{booktabs} in your latex document. When booktabs is not set, xTab looks for the value of kLat.xTab.booktabs, then kLat.booktabs, then defaults to FALSE.

xTab(cars, booktabs = TRUE)
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \toprule
## mpg & cyl & disp & hp & drat \\
## \midrule
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \bottomrule
## \end{tabular}
## \end{center}
## \end{table}

If any of those options are explicitly set, the booktabs value has no effect.

xTab(cars, booktabs = TRUE, midrule = '\\hline')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \toprule
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \bottomrule
## \end{tabular}
## \end{center}
## \end{table}

Table Position

If not set, xTAb will look for the value of kLat.xTab.position. If not set, defaults to 'ht'

xTab(cars, position = '!htbp')
## \begin{table}[!htbp]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

Headers

By default, xTab will use the column names for the head of the table(as demonstrated in the above examples). To customize the table head simply pass in the appropriate latex to the 'head' argument. The values of toprule and midrule are still used and should not be set in the head argument. If you do not want them included in your custom header, set either or both to NULL

xTab(cars,
     head = 'col1 & col 2 & col3 & \\eta & col5 \\\\')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## col1 & col 2 & col3 & \eta & col5 \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

Pass in NULL to avoid a table head. In the case of a NULL head, toprule and midrule will not be used.

xTab(cars, head = NULL)
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

To preserve the top and midrules, pass an empty string to head. Often, people want a toprule with no head or midrule. In that case, pass an empty string into the head argument and NULL into midule. You can then use the default toprule value (as depicted below), explicitly set toprule, or set booktabs = TRUE to set the toprule and bottomrule simultaneously.

lTab(cars, head = '', midrule = NULL)
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## 
## 
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Rows

Rownames

When including row names in a table, by default xTab will use an empty column name for the 'rownames' column. When rows is not set, xTab looks for the value of kLat.xTab.rows, then klat.rows, then defaults to false.

xTab(cars, rows = TRUE)
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
##  & mpg & cyl & disp & hp & drat \\
## \hline
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\
## Hornet 4 Drive & 21.4 & 6 & 258.0 & 110 & 3.08 \\
## Hornet Sportabout & 18.7 & 8 & 360.0 & 175 & 3.15 \\
## Valiant & 18.1 & 6 & 225.0 & 105 & 2.76 \\
## Duster 360 & 14.3 & 8 & 360.0 & 245 & 3.21 \\
## Merc 240D & 24.4 & 4 & 146.7 &  62 & 3.69 \\
## Merc 230 & 22.8 & 4 & 140.8 &  95 & 3.92 \\
## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

Rownames with custom header

When providing a custom head with rows set to TRUE, remember to account for the extra column produced by the row names

xTab(cars,
     rows =  TRUE,
     head = 'rows & col1 & col2 & col3 & \\eta & col5 \\\\')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## rows & col1 & col2 & col3 & \eta & col5 \\
## \hline
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\
## Hornet 4 Drive & 21.4 & 6 & 258.0 & 110 & 3.08 \\
## Hornet Sportabout & 18.7 & 8 & 360.0 & 175 & 3.15 \\
## Valiant & 18.1 & 6 & 225.0 & 105 & 2.76 \\
## Duster 360 & 14.3 & 8 & 360.0 & 245 & 3.21 \\
## Merc 240D & 24.4 & 4 & 146.7 &  62 & 3.69 \\
## Merc 230 & 22.8 & 4 & 140.8 &  95 & 3.92 \\
## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \hline
## \end{tabular}
## \end{center}
## \end{table}

Row separator

Any arbitrary latex command can be inserted between each row, but the most common are \hline and \midrule. To use \midrule, \usepackage{booktabs} must be declared in the preamble of the latex document, but booktabs = TRUE does not need to be set on the table. When rowsep is not set, xTab looks for the value of kLat.xTab.rowsep, then kLat.rowsep, then defaults to an empty string.

xTab(cars, rowsep = '\\hline')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## 21 & 6 & 160 & 110 & 3.9 \\\hline
## 21 & 6 & 160 & 110 & 3.9 \\\hline

Columns

Column alginment

Explicilty set the column definitions. If this is set, colsep will have no effect and you must handle column separation within this declaration. Defaults to 'r' for numeric vector columns and 'l' for character vector columns.

xTab(cars, coldef ='rlc|l|p{5cm}')
## \begin{table}[ht]
## \begin{center}
## \begin{tabular}{rlc|l|p{5cm}}

sTab

sTab is a function that produces a supertabular environment

Basics

Standard sTab table

To produce a latex table, simply pass a matrix or a data.frame to the sTab function.

sTab(cars)
## \tablehead{\hline
## mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\

sTab(cars, label = 'tab:mytable')
## \tablehead{\hline
## mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}

## \end{center}

Booktabs

Setting booktabs = TRUE sets the defaults of the toprule, midrule, and bottomrule arguments to \toprule, \midrule, and \bottomrule respectively. When using booktabs rules, regardless of whether you set booktabs = TRUE or set them individually, make sure to include \usepackage{booktabs} in your latex document. When booktabs is not set, sTab looks for the value of kLat.sTab.booktabs, then kLat.booktabs, then defaults to FALSE.

sTab(cars, booktabs = TRUE)
## \tablehead{\toprule
## mpg & cyl & disp & hp & drat \\
## \midrule}
## \tabletail{\bottomrule}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\

## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

If any of those options are explicitly set, the booktabs value has no effect.

sTab(cars, booktabs = TRUE, midrule = '\\hline')
## \tablehead{\toprule
## mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\bottomrule}
## \begin{center}

## \end{supertabular}
## \end{center}

Headers

Head

By default, sTab will use the column names for the head of the table(as demonstrated in the above examples). The head argument is diplayed at the top of the table on each page that the table spans. To customize the table head simply pass in the appropriate latex to the 'head' argument. The values of toprule and midrule are still used and should not be set in the head argument. If you do not want them included in your custom header, set either or both to NULL

sTab(cars,
     head = 'col1 & col 2 & col3 & \\eta & col5 \\\\')
## \tablehead{\hline
## col1 & col 2 & col3 & \eta & col5 \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

Pass in NULL to avoid a table head. In the case of a NULL head, toprule and midrule will not be used.

sTab(cars, head = NULL)
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

To preserve the top and midrules, pass an empty string to head. Often, people want a toprule with no head or midrule. In that case, pass an empty string into the head argument and NULL into midule. You can then use the default toprule value (as depicted below), explicitly set toprule, or set booktabs = TRUE to set the toprule and bottomrule simultaneously.

sTab(cars, head = '', midrule = NULL)
## \tablehead{\hline
## 
## }
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

FirstHead

In a supertabular environment, it is possible to present a different first head (i.e. header on first page of table only).

sTab(cars,
     firsthead = 'f1 & f2 & f3 & f4 & f5 \\\\')
## \tablefirsthead{\hline
## f1 & f2 & f3 & f4 & f5 \\
## \hline}
## \tablehead{\hline
## mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

Important Note

As demonstrated in the above example, both head and firsthead use the toprule and midrule commands by default. If you desire to use different commands for the head and firsthead (or if you want one, but not both to use a top and midrule), you must set both toprule and midrule to NULL and manually insert the commands into head and firsthead as shown below examples.

sTab(cars, toprule = NULL, midrule = NULL,
     firsthead = '\\toprule\nf1 & f2 & f3 & f4 & f5 \\\\\nmidrule',
     head = '\\hline\n col1 & col2 & col3 & cll4 & col5 \\\\\n\\hline')
## \tablefirsthead{
## \toprule
## f1 & f2 & f3 & f4 & f5 \\
## midrule
## }
## \tablehead{

## \end{center}

Rows

Rownames

When including row names in a table, by default sTab will use an empty column name for the 'rownames' column. When rows is not set, sTab looks for the value of kLat.sTab.rows, then klat.rows, then defaults to false.

sTab(cars, rows = TRUE)
## \tablehead{\hline
##  & mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\

## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

Rownames with custom header

When providing a custom head with rows set to TRUE, remember to account for the extra column produced by the row names

sTab(cars,
     rows =  TRUE,
     head = 'rows & col1 & col2 & col3 & \\eta & col5 \\\\')
## \tablehead{\hline
## rows & col1 & col2 & col3 & \eta & col5 \\
## \hline}
## \tabletail{\hline}
## \begin{center}
## \begin{supertabular}{rrrrr}
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\
## Hornet 4 Drive & 21.4 & 6 & 258.0 & 110 & 3.08 \\
## Hornet Sportabout & 18.7 & 8 & 360.0 & 175 & 3.15 \\

## Merc 230 & 22.8 & 4 & 140.8 &  95 & 3.92 \\
## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{supertabular}
## \end{center}

Row separator

Any arbitrary latex command can be inserted between each row, but the most common are \hline and \midrule. To use \midrule, \usepackage{booktabs} must be declared in the preamble of the latex document, but booktabs = TRUE does not need to be set on the table. When rowsep is not set, sTab looks for the value of kLat.sTab.rowsep, then kLat.rowsep, then defaults to an empty string.

sTab(cars, rowsep = '\\hline')
## \tablehead{\hline
## mpg & cyl & disp & hp & drat \\
## \hline}
## \tabletail{\hline}
## \begin{center}

Columns

Column alginment

Explicilty set the column definitions. If this is set, colsep will have no effect and you must handle column separation within this declaration. Defaults to 'r' for numeric vector columns and 'l' for character vector columns.

sTab(cars, coldef ='rlc|l|p{5cm}')
## \tablehead{\hline

lTab

lTab is a function for creating a longtable environment

Basics

Standard lTab table

To produce a latex table, simply pass a matrix or a data.frame to the lTab function.

lTab(cars)
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Labels

Pass a string into the 'label' option. When not set, defaults to NULL.

lTab(cars, label = 'tab:mytable')
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \label{tab:mytable}
## \end{longtable}
## \end{center}

Captions

The lTab environment can place a caption in the head, firsthead, foot, or last foot. When placing captions in the firsthad or lastfoot, it is important to set these options (even if they are empty strings) or strange bugs can occur.

lTab(cars, caption.head = 'my caption in head')
## \begin{center}
## \begin{longtable}{rrrrr}
## \caption{my caption in head}\\
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\

Booktabs

Setting booktabs = TRUE sets the defaults of the toprule, midrule, and bottomrule arguments to \toprule, \midrule, and \bottomrule respectively. When using booktabs rules, regardless of whether you set booktabs = TRUE or set them individually, make sure to include \usepackage{booktabs} in your latex document. When booktabs is not set, lTab looks for the value of kLat.lTab.booktabs, then kLat.booktabs, then defaults to FALSE.

lTab(cars, booktabs = TRUE)
## \begin{center}
## \begin{longtable}{rrrrr}
## \toprule
## mpg & cyl & disp & hp & drat \\
## \midrule
## \endhead
## \bottomrule
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\

## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

If any of those options are explicitly set, the booktabs value has no effect.

lTab(cars, booktabs = TRUE, midrule = '\\hline')
## \begin{center}
## \begin{longtable}{rrrrr}
## \toprule
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead

## \end{longtable}
## \end{center}

Headers

Head

By default, lTab will use the column names for the head of the table(as demonstrated in the above examples). The head argument is displayed at the top of the table on each page that the table spans. To customize the table head simply pass in the appropriate latex to the 'head' argument. The values of toprule and midrule are still used and should not be set in the head argument. If you do not want them included in your custom header, set either or both to NULL

lTab(cars,
     head = 'col1 & col 2 & col3 & \\eta & col5 \\\\')
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## col1 & col 2 & col3 & \eta & col5 \\
## \hline
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Pass in NULL to avoid a table head. In the case of a NULL head, toprule and midrule will not be used.

lTab(cars, head = NULL)
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

To preserve the top and midrules, pass an empty string to head. Often, people want a toprule with no head or midrule. In that case, pass an empty string into the head argument and NULL into midule. You can then use the default toprule value (as depicted below), explicitly set toprule, or set booktabs = TRUE to set the toprule and bottomrule simultaneously.

lTab(cars, head = '', midrule = NULL)
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## 
## 
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

FirstHead

In a supertabular environment, it is possible to present a different first head (i.e. header on first page of table only).

lTab(cars,
     firsthead = 'f1 & f2 & f3 & f4 & f5 \\\\')
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## f1 & f2 & f3 & f4 & f5 \\
## \hline
## \endfirsthead
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead
## \hline
## \endfoot
## 21 & 6 & 160 & 110 & 3.9 \\
## 21 & 6 & 160 & 110 & 3.9 \\
## 22.8 & 4 & 108 & 93 & 3.85 \\
## 21.4 & 6 & 258 & 110 & 3.08 \\
## 18.7 & 8 & 360 & 175 & 3.15 \\
## 18.1 & 6 & 225 & 105 & 2.76 \\
## 14.3 & 8 & 360 & 245 & 3.21 \\
## 24.4 & 4 & 146.7 & 62 & 3.69 \\
## 22.8 & 4 & 140.8 & 95 & 3.92 \\
## 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Important Note

As demonstrated in the above example, both head and firsthead use the toprule and midrule commands by default. If you desire to use different commands for the head and firsthead (or if you want one, but not both to use a top and midrule), you must set both toprule and midrule to NULL and manually insert the commands into head and firsthead as shown below examples.

lTab(cars, toprule = NULL, midrule = NULL,
     firsthead = '\\toprule\nf1 & f2 & f3 & f4 & f5 \\\\\nmidrule',
     head = '\\hline\n col1 & col2 & col3 & cll4 & col5 \\\\\n\\hline')
## \begin{center}
## \begin{longtable}{rrrrr}
## 
## \toprule
## f1 & f2 & f3 & f4 & f5 \\

## \end{longtable}
## \end{center}

Rows

Rownames

When including row names in a table, by default lTab will use an empty column name for the 'rownames' column. When rows is not set, lTab looks for the value of kLat.lTab.rows, then klat.rows, then defaults to false.

lTab(cars, rows = TRUE)
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
##  & mpg & cyl & disp & hp & drat \\
## \hline
## \endhead
## \hline
## \endfoot
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\

## Duster 360 & 14.3 & 8 & 360.0 & 245 & 3.21 \\
## Merc 240D & 24.4 & 4 & 146.7 &  62 & 3.69 \\
## Merc 230 & 22.8 & 4 & 140.8 &  95 & 3.92 \\
## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Rownames with custom header

When providing a custom head with rows set to TRUE, remember to account for the extra column produced by the row names

lTab(cars,
     rows =  TRUE,
     head = 'rows & col1 & col2 & col3 & \\eta & col5 \\\\')
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## rows & col1 & col2 & col3 & \eta & col5 \\
## \hline
## \endhead
## \hline
## \endfoot
## Mazda RX4 & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Mazda RX4 Wag & 21.0 & 6 & 160.0 & 110 & 3.90 \\
## Datsun 710 & 22.8 & 4 & 108.0 &  93 & 3.85 \\
## Hornet 4 Drive & 21.4 & 6 & 258.0 & 110 & 3.08 \\

## Merc 280 & 19.2 & 6 & 167.6 & 123 & 3.92 \\
## \end{longtable}
## \end{center}

Row separator

Any arbitrary latex command can be inserted between each row, but the most common are \hline and \midrule. To use \midrule, \usepackage{booktabs} must be declared in the preamble of the latex document, but booktabs = TRUE does not need to be set on the table. When rowsep is not set, lTab looks for the value of kLat.lTab.rowsep, then kLat.rowsep, then defaults to an empty string.

lTab(cars, rowsep = '\\hline')
## \begin{center}
## \begin{longtable}{rrrrr}
## \hline
## mpg & cyl & disp & hp & drat \\
## \hline
## \endhead

Columns

Column alginment

Explicilty set the column definitions. If this is set, colsep will have no effect and you must handle column separation within this declaration. Defaults to 'r' for numeric vector columns and 'l' for character vector columns.

lTab(cars, coldef ='rlc|l|p{5cm}')
## \begin{center}
## \begin{longtable}{rlc|l|p{5cm}}
