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.

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. -- Kenneth Roy Cabrera Torres Universidad Nacional de Colombia Sede Medellin Tel 430 9351 Cel 315 504 9339 ______________________________________________ R-help at stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
