Using ESS, If you are editing a org file file via tramp, editing an R src code block should “just work” to start the attached R session remotely.  I do it all the time.

Try this: make sure you do NOT have a local R session already and edit your source block….

Subject: [O] remote R session

Hi there, 

I was wondering how to automatically fire up a remote R session when editing source code in babel source code block? I'd like to have everything on server and be able to play with it including making plots. Currently I do tangle to a file on server first and then use tramp to access it.  Although I get a remote R session, the problem is that I'll be working on a generated copy. Any ways to make improve this ? 

Thanks,

Zhihao
