[R] Memory question

[Kenneth Roy Cabrera Torres]

Hi R users and developers:

I want to know how can I save memory in R
for example:
  - 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.
