:What about installing a recent version of rgl, compiled for R-2.0.x?

:install.packages("rgl") should do the trick.

Got it and now it all works....BUT I'm puzzled by the fact that I systematically
update all the packages in R 2.0.1 using 'update.packages()'. Why in this
case R was unable to find the obsolete versions of Rcmdr and rgl and substitued
the with new ones?

Thanks
