Thanks! 'a' is a factor, thus you are getting the underlying numeric code as the output. Note from ?cat: Currently only atomic vectors (and so not lists) and names are handled. Character strings are output ‘as is’ (unlike print.default which escapes non-printable characters and backslash — use encodeString if you want to output encoded strings using cat). Other types of R object should be converted (e.g. by as.character or format) before being passed to cat. Thus: var - factor(a, levels = c(a, b, c)) var [1] a Levels: a b c is.vector(var) [1] FALSE So 'var' is not an atomic vector and you must therefore coerce it to a character vector using as.character() before passing it to cat(): cat(VAR: , as.character(var), \n) VAR: a HTH, Marc Schwartz __ 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.

R is treating tablea[,1] as a factor. Try converting it to character. --- Carla Rebelo [EMAIL PROTECTED] wrote: Good morning!
