If you apply as.numeric() to a factor, you won't get a zero value. Internal factor values start at 1. So I wouldn't rely on the internal storage to achieve whatever it is you want to achieve. Use explicit computation, e.g. words <- ifelse(var == 0, "Bad", ifelse(var == 1, "Good", NA)) values <- ifelse(words == "Bad", 0, ifelse(words == "Good", 1, NA)) Duncan Murdoch ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
