A MUCH cleaner solution comes directly from the help for c(): ## append to a list: ll <- list(A = 1, c="C") ## do *not* use c(ll, d = 1:3) # which is == c(ll, as.list(c(d=1:3)) ## but rather c(ll, d = list(1:3))# c() combining two lists So in your case results2 <- c(temp, list(c)) Petr > > ------------------------------------------------------------------- > Rajarshi Guha <[EMAIL PROTECTED]> > GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04 06F7 1BB9 E634 9B87 56EE > ------------------------------------------------------------------- > Does Ramanujan know Polish? > -- E.B.
