Is there some convenient way to convert rmarkdown to pandoc markdown?

Question

I use rstudio to write r-markdown , but sometimes it is not compatible with markdown support by pandoc (math for example. If there is a way allow me to convert r-markdown to pandoc markdown, then it will be convenient to export my articles to pdf , org , rts , latex ...

https://pandoc.org/ also seems doesn't mention rmarkdown support.

I have tried to export .html form rstudio and use pandoc convert the html file back to markdown, but it seems doesn't work.

Actually pandoc is used to create pdf and other formats from r-markdown. Therefore there is an intermediate file with pandoc compatible markdown. You could retain this file by:

rmarkdown::render("document.Rmd", output_format = "pdf_document", run_pandoc = FALSE)
