Hello, I have been surprised when converting a character string to a date with the following format,
in R 4.1.0 (linux debian 10) as.Date("20-12-2020","%Y-%m-%d") [1] "20-12-20" in R 4.0.5 (window 10) as.Date("20-12-2020","%Y-%m-%d") [1] "0020-12-20" Here I was expecting a blunt and sharp NA, am I missing something? Best regards, Jeremie ______________________________________________ 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.
