It is easy to use latexTable()
in R Markdown documents, provided that
you are generating LaTeX or PDF files from those R Markdown documents. To do
so, you need to take only two steps: load a file via the in_header
option
for R Markdown documents, and wrap your latexTable()
output in the
raw_latex()
command that is provided by the knitr
package.
To use latexTable()
in R Markdown documents, certain LaTeX packages must be
loaded: the afterpage, array, booktabs, caption, numprint
and ragged2e
packages. Depending on the options that you specify in your latexTable()
call, you may also need to load the afterpage
, float
, and pdflscape
packages.
The Bullock
package comes with a file, latexTable_RMarkdown_preamble.tex
,
that loads all of these packages. Thus, to load the packages, you need only
tell R Markdown to load latexTable_RMarkdown_preamble.tex
. The best way to
do this is by using the in_header
option in the header of your R Markdown
document. The header should look like this:
--- title: "Test latexTable() Output" output: pdf_document: includes: in_header: !expr system.file("latexTable_RMarkdown_preamble.tex", package = "Bullock", mustWork = TRUE) ---
latexTable()
output into an R Markdown documentTo insert latexTable()
output into your R Markdown document, just wrap
the output in a raw_latex()
command:
library(Bullock) library(knitr) myTable <- latexTable(matrix(1:16, nrow = 4)) raw_latex(myTable)
Remember that if you are using multiple tables, you will need to specify
a unique LaTeX name for each one (by using the commandName
argument in your
latexTable()
calls).
latexTable()
output into a Sweave / Rnw document.LaTeX documents that contain embedded R code chunks are sometimes called
"Sweave" documents, and they typically have the extension .Rnw
. The
procedure for embedding latexTable()
output into these documents is just
a little different:
cat('<<myTable, echo = FALSE, results = "asis">>=') cat('library(Bullock)') cat('library(knitr)') cat('myTable <- latexTable(matrix(1:16, nrow = 4))') cat('cat(myTable, sep = "\\n")') cat('@')
The most obvious limitation is that latexTable()
cannot be used when
generating HTML documents from R Markdown. It will work only when generating
LaTeX or PDF from R Markdown.
