[R-sig-mediawiki] Sometimes the R display has "memory" and does not update

[Xiaoxu LI]

Dear R extension folks,

Several times I visited
http://mars.wiwi.hu-berlin.de/mediawiki/slides/index.php?title=Comparison_of_noncentral_and_central_distributions
and click some button to view interactive result, I found the version
shown in R display was of not obsolete version. My trick was to change
name of RForm and R display to cut off the R display's memory.
