[R] RGtk2 problems

[Prof Brian Ripley]

Please update your R (and probably your RGtk2: you did not tell us its 
version), as the posting guide asked you to do before posting.

As a binary package, I guess, but please tell us (it matters).

But you need the Gtk+ bin directory in your PATH.  Environment 
variable GTK_PATH is only needed when RGtk2 is installed from the 
sources.

Which Gtk+ you need in your path depends on the version of RGtk2 you 
have and how you installed it.  For current binary versions, see
