str(c3) Date[1:1], format: "2009-10-01" A.K. ----- Original Message ----- From: paladini <palad...@beuth-hochschule.de> To: r-help@r-project.org Cc: Sent: Monday, July 23, 2012 9:05 AM Subject: [R] date conversation Hello, when I convert a factor like this a=01.10.2009 into a date using b=strptime(a, format="%d. %m. %Y"). It works very well. But when I try to convert c = 2009/10 into a date using d=strptime(c, format="%Y/%m") it doesnt work at all. I get d=NA. What did I do wrong? Thank you very much for your help! best regards Claudia ______________________________________________ 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. ______________________________________________ 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.
