Matthew,

Did you take a look at the R.huge package?  It works well with numerical
data.

If you describe the problem you're trying to solve in more detail, it may
help us give you a better solution.

Btw, we use the filehash package with great success in accessing very large
amounts of data.

Best,
Adrian Dragulescu
