Do you notice this:

cd into a folder, say "~/tmp/project/R" and start emacs with a file in
there. The working directory correctly shows "~/tmp/project/R".

Then launch an R session. When you quit the R session, and start a new
R session, the working directory changed, it becomes "~/tmp/project".

This is just a little inconvenient if you get an R session with some
crap in it and you close it down to start fresh, but the WD is no
longer correct. Its necessary to close emacs and re-open the file.

I'll paste in the Emacs session transcript to show what I mean. The
only thing I do after the q() is hit the big blue R button:


> getwd()
[1] "/home/pauljohn/GIT/rockchalk/package/rockchalk/R"
> q()
Save workspace image? [y/n/c]: n
