I just wasted a dozen hours scattered over several days testing out vim instead of r-studio for when I am writing longer reports with a lot of text in markdown as well as code. My motivation was this:
So I went through all the hassle of installing vim (and gvim for a more graphical approach) on my ubuntu box. I got R integration working OK in gvim, Tried voom http://www.vim.org/scripts/script.php?script\_id=2657 for additional outlining support but it didn’t work properly for me. Tried various vim plug-ins to get syntax highlighting and folding to work in vim, such as https://github.com/plasticboy/vim-markdown/blob/master/after/ftplugin/mkd.vim. Managed to get ftplugin to work OK on .md files but not on .Rmd files, which is what I need for R. Likewise, I couldn’t get R integration to work for .md files.
More importantly though, I just don’t see that these kinds of clunky folding solutions come anywhere near the outline dream of Word (or freeplane for that matter). You can’t promote, demote sections, move up and down, etc. Not worth changing my whole workflow away from Rstudio.
Then I took a minute to read the documentation and changelog for Rstudio and realised that the newer versions have support for sections in code which work outside code chunks, and are sort-of compatible with markdown. So at least I can expand and collapse all markdown sections, which is pretty good. Plus, I realised that you can indeed move the console to its own vertical pane (perhaps you could always do this and I just missed it).
So here I am back with Rstudio and pretty happy all round.
