This would be great, do any other language bundles have a similar feature?
I'd like to be able to get any help on the selected word, preferably
the local (harddrive) help but the web would be fine.

This shouldn't be too difficult, there is a shell command for running
R code.  R CMD BATCH.

You can make these yourself.  I did for '<-' which I assigned to
space-tab.  I rarely use '->' except interactively.  What other
snippets have people written for R?

I imagine this would be difficult because each package can have
different syntax requirement, can you be more specific by what you are
looking for?

I would like a quicker way to send the current selection to R.app.  I
don't know if this is possible, but the current method can be sluggish
for longer scripts.

I also modified the language definition to include parenthesis for
folding as often my plot command span several lines and it's nice to
hide them.
