What can be wrong? I already deleted R and its folder and installed it
fresh. Same problem. On an XP machine this never happened. :-( Thank
you for your help.


The function has written you what was wrong.
"C:/PROGRA~1/R/R-25~1.1/library"' was not writable

You should install new packages either running R with administrator
privilegies, or installing them to another directory, writable for ordinary
user.
