i have a column of dates in this format: data[,"Raised.Date"] <- as.Date(data[,"Raised.Date"], "%d/%m/%Y"); data[1:10,"Raised.Date"] [1] "2006-07-07" "2006-07-07" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03"
I can turn them into months like this... Month<-months(data[,"Raised.Date"]) Month[1:10] [1] "July" "July" "April" "April" "April" "April" "April" "April" "April" "April" But i also want to turn them into years (and also weeks later on), so tried this... Year<-year(data[,"Raised.Date"]) Error: could not find function "year" thanks. -- View this message in context: http://n4.nabble.com/column-of-dates-into-time-series-tp930699p930699.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
