R help - Jan 2012 - repeat function for entire list of matrices

hi all.

perhaps someone can help me with subsetting here............

i'm trying to use the nested() function in the bipartite package.  my
problem is that i have a list of 10,000 matrices and i want the output to be
a vector of the nested() function on each of the 10,000 matrices (so i can
use these numbers in a statistical test).

here is what i'm working with currently:

#to store 10,000 matrices of null.distr() in listofmatrices
listofmatrices <- null.distr(10000,matrix_here,distr="lognormal")

#to select nth matrix from listofmatrices
nested(listofmatrices [[n]],method="binmatnest2")

so this give me an output for that one matrix i selected.  i want to
calculate the nested() value for ALL the matrices 

since i have 10,000 matrices in listofmatrices, i dont want to have to
repeat this from n=1....9,999, 10,0000 and store each of the nested()
values.

any help???

?lapply

Perhaps (untested):

lapply(listofmatrices, nested, method="binmatnest2")
