Preview tables in a TeX article — st2article • pmtables

Use st2article() to see tables in a plain pdf TeX document. Use st2report() to see tables in a more formal, report-like document. st2article() might have a slight speed advantage for shorter development cycle and simpler presentation. See details.

st2article(
  ...,
  .list = NULL,
  ntex = 1,
  stem = "view-st2article",
  output_dir = tempdir(),
  template = NULL,
  margin = c("2.54cm", "3cm"),
  caption = NULL,
  dry_run = FALSE,
  stdout = FALSE,
  show_pdf = TRUE
)

st2report(
  ...,
  .list = NULL,
  template = "report.tex",
  caption = Lorem,
  stem = "view-st2report"
)

Arguments

...	stable objects
.list	a list of stable objects
ntex	number of times to build the pdf file
stem	name for the article file, without extension
output_dir	the output directory for the rendered pdf file
template	an optional template for rendering the article; this normally shouldn't be used
margin	the page margins; this must be a character vector of length 1 or 2 specifying the page margins; if length is 1, the data will be recycled into the second position (e.g. equal margins left/right and top/bottom); if length is 2, use the first position to set left & right margins and the second position to set top & bottom margins; when specifying the margin size, include both the number and the unit (e.g. `3cm` or `1in`; you must enter the unit and the input must be character)
caption	placeholder text to be included as a caption; this text will be used for every table that is passed in; this isn't intended to be the actual caption for the table, but just placeholder text as you preview the appearance of the table
dry_run	if `TRUE`, then the document and table code are returned (visibly) and no attempt is made to try to pass the document through `pdflatex`
stdout	passed to `system2()`; by default, the `pdflatex` build output is suppressed; if you are having difficulty generating a pdf document, set `stdout = ""` and you'll see the output in the R console
show_pdf	if `TRUE`, then the rendered pdf file will be opened using `fs::file_show()`

Value

If dry_run is FALSE, then a list (invisible) containing the document template as doc and the table data as tables. If dry_run is TRUE, then the doc and tables are returned visibly (see dry_run argument).

A list of the table inputs, invisibly.

Details

This is experimental. Pass in either stable or stable_long objects, and st2article() or st2report() will write the output to temporary file and render the collection of tables in a pdf document without using Rmarkdown or pandoc. The rendering is accomplished through system call to pdflatex.

A working tex distribution is required to run this function.It is important to review the different latex dependencies in the document template. It is assumed that all of these dependencies are available. See examples below for code to open the template for review.

This function requires pdflatex to be installed and in your path to build the document. Run system2("pdflatex", "-v") to see if pdflatex properly installed.

This function requires specific packages to be available. Review the tex template files in /inst/article for a complete specification of the requirements. If a requirement is not available, the document will not build.

To render a table in landscape environment, pass the stable object through as_lscape.

Examples

template_file <- system.file("tex", "article.tex", package = "pmtables")
template_contents <- readLines(template_file)

template_file <- system.file("tex", "report.tex", package = "pmtables")
template_contents <- readLines(template_file)

if (FALSE) {
  tab <- stable(ptdata())
  pmtables::st2article(tab)
}
