I'm not sure if I have understood your question, so I will put two possibilities: 1 - You have a variable called X ="0" and a variable called Y = "12" and want that to be numeric. You can do this: X <- as.numeric(X) Y <- as.numeric(Y) 2 - You have a variable called XY = "0","12" and want to make a list of numeric. Then you can do something like this: XY <- as.numeric(unlist(strsplit(XY, ","))) I hope this helps, Best regards Jorge Aikes Junior -- View this message in context: http://r.789695.n4.nabble.com/How-to-set-values-tp3823290p3848526.html Sent from the R devel mailing list archive at Nabble.com.
