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

I played myself a little bit with forced reload. If I change the program 
code, e.g. by adding a blank, then a new content is generated by the R 
program. Then I ran several time the program by clicking on the buttons 
and made finally a forced reload. And I got in the iframe content when 
the modified program (adding a blank) was saved.

I guess the problem is somewhere in the interplay between apache, the R 
extension PHP script and the mediawiki code. And I'am not sure if the R 
extension PHP code can influence this. Also the web browser itself 
forces a reload sometimes, depending on your  browser options.

So, the best advice I can give you: Do not rely on the contents of the 
iframe and if necessary tell a user which buttons to press to get the 
result you except to be in the iframe. For documents with interactive 
examples it is generally problem to know what is the current contents of 
the example. And a wiki alone is not made for handling these kind of 
problems.

Sorry, that I can not help you better
