Consider sending this sort of question to R-help as it has nothing
BioC specific...

Are all elements the same length?  If not, is the assumption that you
want to pad the end of short vectors with NA?

We'll use a helper from Biobase to make this BioC specific ;-)

library("Biobase")
length(unique(listLen(aList))) == 1

You could make a matrix like this:

  mat <- do.call(cbind, aList)
  write.table(mat)

If lengths are not equal...

lens <- listLen(aList)
nRows <- max(lens)
bList <- lapply(aList, function(x) {
    if (length(x) != nRows)
        c(x, rep(NA, nRows - length(x)))
    else
        x
})
