Re: [R] Joining variables
Hello, Although I cannot speak for the original individual posting this question but I would like to see an example, if possible, of how to construct a factor of several factors. I think this would be more efficient than "paste" if such a procedure were possible and, of course, would also answer the postee's original question.

What does "combination of both" mean exactly. I can think of two interpretations that have two different answers.

See ?paste or ?sprintf
Var1 <- factor("SA100055113")
Var2 <- 19851113
NewVar <- paste(Var1, Var2, sep = "")
NewVar <- sprintf("%s%s", Var1, Var2)

[R] Joining variables
Hello, If I have two variables that are factors or characters and I want to create a new variable that is the combination of both what function can I use to accomplish this? Ex. Var1Var2 SA100055113 19851113 And I want NewVar SA10005511319851113 Thanks in advance. Cameron Guenther, Ph.D. Associate Research Scientist FWC/FWRI, Marine Fisheries Research 100 8th Avenue S.E.
