TIA
Use file.info and check the $isdir part of the returned data frame. For example, to get names of only directories in your working dir, do: row.names(subset(file.info(list.files(getwd(),full.name=TRUE)),isdir)) a quick modification gets you not-directories (which will be plain files plus special files): row.names(subset(file.info(list.files(getwd(),full.name=TRUE)),!isdir)) see ?file.info and ?files Barry ______________________________________________ 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.
