[R] calculating mean of list components

I get a list object from an iterative function. I'm trying to figure
out the most efficient way to calculate the mean of one element, across
all components of the overall list.
output <- mean (listobject[[1:5]]$element)
to get the mean of "element" in the first five components?
It doesn't like the $. I'm suspect one of the "apply" functions will
work, but again I've not had success
Thanks a bunch.
