R help - Sep 2003 - storing objects (lm results) in an array

Hi

I have calculated lots (>1000) of linear models and would like to store
each single result as an element of a 3D matrix or a similar storage:
something like

glm[i][j][k] = lm(...)

Since I read that results are lists: Is it possible to define a matrix
of type list? 

Or what do you recommend?

Many thanks

Christoph

1) glm is already a function name in R.  I'd suggest a different name.

2) I don't recommend a matrix.  Matricies require contiguous memory
chunks - it's possible to not have a long enough "block" of memory
available, even when the total free memory is sufficient, when storing
large matricies.

What's wrong with nested lists?  Something like my.lms[[i]][[j]][[k]] <-
lm(...)

This can "scatter" its storage across discontinuous chunks of memory.

Cheers
