[R] ggplot2 problem in interacting mode

[Ista Zahn]

Hi,
Here are a couple of suggestions:
 -- Start R without loading startup scripts etc. (R --vanilla) and see
if it works. If yes, there is something loading in your startup file
or restored environment that is causing problems.
-- Upgrade to the latest version of R

HTH,
Ista
