Rstudio is very likely running the system*() commands and the commands 
setting environment variables in ways that interfere in your case. Start 
by using R from the command line, then RGui, then find out how to debug 
running functions in Rstudio and run initGRASS under the debugger to see 
at which step contact gets lost.

I believe that there are reports of success using Rstudio within GRASS (in 
an existing GRASS location, starting Rstudio within GRASS).

Does anyone have any experience? (I do not use Rstudio, so cannot tell - 
under Linux it wants R built in a specific way that I don't want to be 
forced to change to).
