gentlg: Output a 'tidytlg' table

In tidytlg: Create TLGs using the 'tidyverse'

Output a tidytlg table

Description

Generate and output a huxtable with desired properties During this function call, the huxtable can be written to an RTF or displayed in HTML. gentlg is vectorized, see parameter descriptions to learn for which arguments.

Usage

gentlg(
  huxme = NULL,
  tlf = "Table",
  format = "rtf",
  colspan = NULL,
  idvars = NULL,
  plotnames = NULL,
  plotwidth = NULL,
  plotheight = NULL,
  wcol = 0.45,
  orientation = "portrait",
  opath = ".",
  title_file = NULL,
  file = NULL,
  title = NULL,
  footers = NULL,
  print.hux = TRUE,
  watermark = NULL,
  colheader = NULL,
  pagenum = FALSE,
  bottom_borders = "old_format",
  border_fns = list(),
  alignments = list()
)

Arguments

huxme	(optional) For tables and listings, A list of input dataframes containing all columns of interest. For graphs, either NULL or a list of ggplot objects. Vectorized.
tlf	(optional) String, representing the output choice. Choices are "Table" "Listing" "Figure". Abbreviations are allowed e.g. "T" for Table. Strings can be either upper- or lowercase. Vectorized. (Default = "Table")
format	(optional) String, representing the output format. Choices are "rtf" and "html". Strings can be either upper- or lowercase.(Default = "rtf")
colspan	(optional) A list of character vectors representing the spanning headers to be used for the table or listing. The first vector represents the top spanning header, etc. Each vector should have a length equal to the number of columns in the output data frame. A spanning header is identified through the use of the same column name in adjacent elements. Vectorized.
idvars	(optional) Character vector defining the columns of a listing where repeated values should be removed recursively. If NULL then all column names are used in the algorithm. If NA, then the listing remains as is.
plotnames	(optional) Character vector containing the names of the PNG files, with their extension to be incorporated for figure outputs. The PNG files need to be located in the path defined by the parameter opath.
plotwidth	(optional) Numerical value that indicates the plot width in cm for figure outputs. (Default = 6)
plotheight	(optional) Numerical value that indicates the plot height in cm for figure outputs. (Default = 5)
wcol	(optional) Can be a single numerical value that represents the width of the first column or a vector, specifying the lengths of all columns in the final table or listing. When a single numerical value is used, this will be taken as the column width for the first column. The other columns will be equally spaced across the remainder of the available space. Alternatively, a vector can be used to represent the widths of all columns in the final output. The order of the arguments needs to correspond to the order of the columns in the huxme dataset, that are not part of the formatting algorithms (e.g. anbr, roworder, newpage, newrow, indentme, boldme, by_value, by_order). The sum of the widths in the vector needs to be less or equal to one. When format="HTML" wcol can take only one value, the width of the first column. (Default = 0.45).
orientation	(optional) String: "portrait" or "landscape". (Default = "portrait")
opath	(optional) File path pointing to the output files (including PNG files for graphs). (Default = ".").
title_file	An Excel file that will be read in with readxl::read_excel() to be used as the title and footers argument. The use of title or footers will override the values passed by this argument. The file should be either an xls or xlsx file with the columns ⁠TABLE ID⁠, IDENTIFIER, and TEXT. The file will be read in, subset to where the tblid matches the tlf argument, and identifiers with 'title' or 'footnote' will be used to populate the table.
file	(required) String. Output identifier. File name will be adjusted to be lowercase and have - and ⁠_⁠ removed, this will not affect table title.
title	(required) String. Title of the output. Vectorized.
footers	(optional) Character vector, containing strings of footnotes to be included. Vectorized.
print.hux	(optional) Logical, indicating whether the output should be printed to RTF ('format' = "rtf") or displayed as HTML ('format' = "HTML"). (Default = TRUE). Note that RTF is written using quick_rtf_jnj() function and that the HTML is displayed via the huxtable::print_html function.
watermark	(optional) String containing the desired watermark for RTF outputs. Vectorized.
colheader	(optional) Character vector that contains the column labels for a table or listing. Default uses the column labels of huxme. Vectorized.
pagenum	(optional) Logical. When true page numbers are added on the right side of the footer section in the format page x/y. Vectorized. (Default = FALSE).
bottom_borders	(optional) Matrix or "old_format". A matrix indicating where to add the bottom borders. Vectorized. See add_bottom_borders() for more information. If "old_format", then borders are added to the colspan and colheader rows. (Default = "old_format").
border_fns	(optional) List. A list of functions that transform the matrix passed to bottom_borders. Vectorized. See add_bottom_borders() for more information.
alignments	(optional) List of named lists. Vectorized. (Default = list()) Used to specify individual column or cell alignments. Each named list contains row, col, and value, which are passed to huxtable::set_align() to set the alignments.

Value

A list of formatted huxtables with desired properties for output to an RTF or HTML.

Huxme Details

For tables and listings, formatting of the output can be dictated through the formatting columns (newrows, indentme, boldme, newpage), present in the input dataframe. The final huxtable will display all columns of the input dataframe, except any recognized formatting or sorting columns. For tables, the algorithm uses the column label as first column. The remaining columns are treated as summary columns. For graphs, you can pass a ggplot object directly into huxme and gentlg will save a PNG with with ggplot2::ggsave() and output an RTF.
