In your case, I think you should use df[[2]] <- as.Date(df[[2]], format="%d/%m/%Y")

To print it into another format, see ?format.Date Regards ______________________________________________ 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.
