Dear all, I was exploring the "dopar" mechanism in foreach package, however it seems that "dopar" can be applied only in place of 'for' loop. Here my question is: can it be used with 'lapply' construct?

I have a big 'list' object and I am in some process to apply some complex custom made function on each element of that 'list' object. I have dual core windows vista system, and planning to break that list into 2 part of equal length, then apply that function simultaneously using both cores.

Can somebody throw some light how to achieve that?

Thanks for your help,
