The important thing is that "4" in my example below can be any computable expression: e.g., if you want the last column colnames(dats)[NCOL(dats)] <- ... Alternatively, you can change the name at construction, but I couldn't give you a hint there since you didn't tell us how you went about adding the column. Note something like this though: dts <- data.frame(x = 1:5, y = letters[5:1]) dts2 <- cbind(dts, z = rnorm(5)) print(dts2) Cheers, Michael > > Alok > > On 8/29/2012 12:29 PM, R.
