latexTable()
with R Markdown and Rnw documentsIt 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:
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:
<<myTable, echo = FALSE, results = "asis">>=
library(Bullock)
library(knitr)
myTable <- latexTable(matrix(1:16, nrow = 4))
cat(myTable, sep = "\n")

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.
