R help - Jan 2011 - combining matrices from a list into a multidimensional array

I get some results back from running an iterative analysis in the form of a list
of matrices.  What I would like to do with this list is combine it such that all
the similar components get combined into a multidimensional array.  If possible
I'd like to put results[[1]]$resultmean and results[[2]]$resultmean into a
3x3x2 array, and also put results[[1]]$resultsd and results[[2]]$resultsd in a
separate 3x3x2 array.  I'm sure this has been asked before, can someone
point me in the right direction?

Thanks

Hi:

Try this:

lapply(results, function(x) array(unname(unlist(x)), c(3, 3, 2)))
