I am trying to write a function that makes a matrix out of two lists. As you will see run running the function below, the result is NOT a matrix but rather a list. Can anyone tell me what I am doing wrong? Thanks, John test <- function(one,two) { cat("List One=",one,"\n") cat("List Two=",two,"\n") cat("Should be a matrix, but is not",matrix(cbind(one,two)),"\n") } x <- c(1,2,3) y <- c(11,22,33) test(x,y) John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) Confidentiality Statement: This email message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
