Description

The function is_latex_output() returns TRUE when the output format is LaTeX; it works for both ‘.Rnw’ and R Markdown documents (for the latter, the two Pandoc formats latex and beamer are considered LaTeX output). The function is_html_output() only works for R Markdown documents and will test for several Pandoc HTML based output formats (by default, these formats are considered as HTML formats: c('markdown', 'epub', 'html', 'html4', 'html5', 'revealjs', 's5', 'slideous', 'slidy', 'gfm')).

Usage

Arguments

Details

The function pandoc_to() returns the Pandoc output format, and pandoc_from() returns Pandoc input format. pandoc_to(fmt) allows to check the current output format against a set of format names. Both are to be used with R Markdown documents.

These functions may be useful for conditional output that depends on the output format. For example, you may write out a LaTeX table in an R Markdown document when the output format is LaTeX, and an HTML or Markdown table when the output format is HTML. Use pandoc_to(fmt) to test a more specific Pandoc format.

Internally, the Pandoc output format of the current R Markdown document is stored in knitr::opts_knit$get('rmarkdown.pandoc.to'), and the Pandoc input format in knitr::opts_knit$get('rmarkdown.pandoc.from')

Note

See available Pandoc formats, in Pandoc's Manual
