the plugin looks for R files in its directory, and for the moment the path
points to the user plugin directory. If the plugin is installed in official
plugin folder, it runs but can't call R.
I don't know which OS you are using, nor if the dependencies are the ones I
wrote on the wiki page  and I'm sure they work.
Consider also to get the head revision (I entered testing phase and I update
code often with bugfixes).
If you are using Mac, a full error report will be extremely useful!
