Anyway to limit the number of cores used?

[GBsuperman]

This package is super useful with the wide availability of multi-core windows machines (like my notebook. Thanks!). However, using all of the cores makes it very hard to do other work. So, any solution here?

Cheers, Guangbo

It seems to me you set the number of cores just like in mclapply: via mc.cores
