R help - Jul 2010 - using objects from different workspaces

Hi all,

I have the following problem: I need to run a large number of simulations,
therefore I use many computers. After the computations I need to make some
operations with the obtained results (such as weighted average, sum, etc.).

My question is, how is it possible to combine the output of several R
sessions?

My objects are quite complex (multi-dimensional arrays), therefore export to
some simple csv file seems not to be a solution. I also need to do this
operation several times, so it would be good if it could be automatized.

Thank you in advance,
Martin
