unpredictable side-effects but, I think that in this case I don't have to much
chance.
Here is a mock function that pushes the content of a variable evaluated within
a function to the nodes on the cluster, do some compu
Hi Marco --
Do you know about Bioconductor, http://bioconductor.org ? The
rowttests function in the genefilter package will do what you want
efficiently and on a single node.

Dear R gurus,
I have a very embarrassingly parallelizable job that I am trying to speed up
with snow on our local cluster. Basically, I am doing ~50,000 t.test for a
