I've found a problem with either the 'apply' or 'is.factor' functions, and it seems like it might be cause for concern. Here are the commands taken directly from the R session: > is.factor(test.frame[, 1]) [1] TRUE > is.factor(test.frame[, 2]) [1] TRUE > is.factor(test.frame[, 3]) [1] TRUE > is.factor(test.frame[, 4]) [1] TRUE > apply(test.frame, 2, is.factor) X1 X2 X3 X4 FALSE FALSE FALSE FALSE All of the variables in test.frame are factors, and is.factor returns TRUE when it's used on each factor individually. When it's used inside of apply, all of the variables return the value FALSE. So there's something wrong in at least one of these functions. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
