[R] Memory question

One way I do this is to use Luke Tierney's "active bindings". I make an
active binding of a name to a function which either loads or saves the
object. Then the name behaves like the R object it's replacing. This works
nicely as long as I don't need lots of random accesses to the matrix.
I'd be happy to send the functions I use to do this.

Subject: [R] Memory question
Hi R users and developers:
I want to know how can I save memory in R
- saving on disk a matrix.
- using again the matrix (changing their values)
- saving again the matrix on disk in a different file.
The idea is that I have a process that generate several
matrices, but if I keep them all in memory it will overflow.
How can I save them in different files, so I use the same
amount of memory for each processed matrix?
Thank you for your help.
