[R] for help!

[jbwu]

hi, Guys:
Now I am trying to use "R" to do some canonical analysis on large data sets,
one of them is 42MB, and can be read by "R", the other data file is about 90MB,
and this time R cannot read such a big size data. My question is that how can
I deal with such a big dataset with "R", or are there any other statistical 
softwares
which can read a huge data file as I memtioned?

Thank you
