[R] problems in loading MASS

[Charilaos Skiadas]

Weiwei,

	I have never had much success installing packages from within R.app  
on MacOSX, because the location that it is supposed to save things, / 
Library/Frameworks/...., needs elevated priviledges, which the app  
doesn't seem to try to get.  So it at best ends up saving it in some  
temporary location, and it has to be downloaded again next time R is  
restarted.

As a result, I have always downloaded the tgz file from my browser,  
then go to the terminal in that folder and do a "sudo R CMD INSTALL  
packagename.tgz".

But perhaps I am doing something wrong and one can do this properly  
from within R.app, I would love to be wrong on this one.
