Hello, You can use function as.yearmon in package zoo to get the correct month/year order. df1 <- data.frame(Year = c(2021, 2021, 2021), Mon = c("Mar", "Jan", "Apr")) df1$mon_year <- zoo::as.yearmon(paste(df1$Mon, df1$Year)) sort(df1$mon_year) #> [1] "Jan 2021" "Mar 2021" "Apr 2021" Hope this helps, Rui Barradas ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
