You can convert R Markdown files to RTF files using the rtf_document
output mode.
Pandoc has limited support for RTF. If you want to create custom RTF output (e.g. using the RTF2 package) then you can effectively bypass the rendering process with the raw_output
function in the knitr
package. See test-rtf.Rmd
for an example. Note: this process currently requires development versions of the rmarkdown
and knitr
pacakges.
