[R] memory problems

[Alex R. Kraaijeveld]

Hi all

New to R, and to this list, so this may be an old (and hopefully simple to solve!) problem.

When running an aov analysis, after fitting two-way interactions, I get an error message saying 'can not allocate vector of 8515Kb'. Often other programs are then kicked out of memory or the whole computer crashes. I've tried bumping up memory by adding max-mem-size, max-vsize, min-vsize, max-nsize, min-nsize, etc commands (with parameter values up to 1G) to the start-up line, but that either doesn't work or makes matters worse (i.e analysis crashes earlier).

Our computer support officer here has looked at the problem and he does not believe it has to do with the actual amount of physical RAM of my machine, but more with the way R handles memory. I run R under Windows NT, by the way.

Any suggestions as to what I'm doing wrong?

Thanks for any help!
Lex
