sorry, I am trying to analize an expression microarray of nearly 350
samples. My R version is R 2.10.1 GUI 1.31 Leopard build 32-bit (5537). How
do I load R in 64 bit? (maybe this is a trivial question for you but it is
not for me, as I have no computer background).
Thank you very much again,

Hernando
