I did a ?do.call but i don't think i understand it.
if a, b,c,d are numeric vectors then could someone explain the
difference between
do.call("cbind",list(a,b,c,d))
and cbind(a,b,c,d).
or point to an archive on it.
the return value of cbind is a matrix or dataframe depending on what is
sent in but i don't
understand wheen it would be useful to use do.call. i realize it takes a
list but that's
all i know about why one use it ? thanks.
