[R] unable to install package ff

[Matthew Keller]

Hi Adrian et al,

Thanks for the advice. I haven't yet tried R.huge but will do so soon.

I have used filehash and it is working well now. A note: for some
reason, R objects were not being 'flushed' from memory on R 2.5.1 -
even when removed and after an explicit call to gc(). Originally I
thought this was a problem with the filehash library but since found
other instances when it occured and when not using filehash. After
updating to R 2.6.0, this behavior resolved itself. So a note to
others: if you're having problems with memory, you might make certain
your version of R is up-to-date! Was this a documented issue with R
2.5.1?

Best,

Matt
