Hi All, I wanted to to convert character date mm/dd/yy to YYYY-mm-dd The sample data and my attempt is shown below
gs <-read.table(text="ID date A1 09/27/03 A2 05/27/16 A3 01/25/13 A4 09/27/19",header=TRUE,stringsAsFactors=F) Desired output ID date d1 A1 09/27/03 2003-09-27 A2 05/27/16 2016-05-27 A3 01/25/13 2012-04-25 A4 09/27/19 2019-09-27 I used this gs$d1 = as.Date(as.character(gs$date), format = "%Y-%m-%d") but I got NA's. How do I get my desired result? Thank you. ______________________________________________ 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.
