[R] average matrices across a list

[Phil Spector]

Gregory -
    Suppose your list is called "mymats".  Then

Reduce("+",mymats)

does what you want.

This would collapse it down to just one nxm matrix. Any easy ways to do that? As always, I'd like to avoid a for loop to keep computational time low! Thanks again everyone!
