Hi guys,
I just wanted to let you know that I started to realize a Pandoc filter to 
insert R plots in markdown:
https://github.com/cdupont/R-pandoc

I hope it doesn't exist already!! I couldn't find one with Google.
I know about Rmarkdown, but it didn't fit my needs because I wanted to 
combine the filter with other ones.

Best,
Corentin

Great news, I'd find this useful!

It sounds good, but what would push me to use this filter in place of R-markdown and the `knitr` package?

One thought I had is to make the knitr process not necessarily dependent on R, meaning this could be a language-agnostic filter. Perhaps it could be extended to also with with textual output such as tables or just console output. A next step could be to make the script interpreter an argument of the code block.

(By the way, knitr also deals with multiple languages. The bigger justification I can see for using your package is if I want capabilities of a scripting language in the .md file and do not have R available, but that assumes language-agnosticism.)

Cool work.

My main need is to make the filter composable with other filters. I wasn't
able to do that with knitr.
Besides, Rmarkdown/knitr uses a special format Rmd, I find it cleaner to
use only md format because the document might contain other stuff than R
code.

It's for my Hakyll blog, I also did a filter for diagrams (
http://projects.haskell.org/diagrams/):
https://github.com/cdupont/diagrams-pandoc
https://github.com/cdupont/hakyll-diagrams

So now I am able to chain those two filters:

myPandocCompiler = pandocCompilerWithTransformM rOpts wOpts $
diagramsTransformer >=> rTransformer
