Hi, I have the following function: TEST <- cbind(Pox0t30.stone.1990.2000, sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var))) In rhe resulting Object TEST the added column is titled: sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var) I would like to change it to a sensible variable name like PoxMean. How can I incorporate this into the above function? Ulrich -- __________________________________________________ Ulrich Leopold MSc.

Use the fact, that the variable names in a data.frame (and in a matrix too) are store as the second component in the list dimnames(TEST). So you could try e.g. dimnames(TEST)[[2]][length(dimnames(TEST)[[2]]) <- "PoxMean" Cheers, Ott -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
