[R] list structure question

  I have a list in which element is a vector (all of the same length and
all numeric). I want to find the mean of the first elements of the
vectors, the mean of the second elements of the vectors and so on.

Currently I convert the list to a data.frame and apply rowMeans(). But
is there a way to to do this directly on the list? I seem to recall a
post in which there was such a function (or expression) but I just cant
seem to find it.

Could somebody point me in the right direction?
