How can I cbind three or more matrices like A,B and C. This does not work:

cbind(A,B,C)

Thanks,

A, B, C should have the same number of rows.

mlist = replicate(3, matrix(rnorm(6), 2), simplify=FALSE)
names(mlist) = LETTERS[seq_along(mlist)]
with(mlist, cbind(A,B,C))

or,

do.call(cbind, mlist)

Jim -
    In what sense does cbind(A,B,C) not work?
