Hi,
I have date and time in a format like this: " 2007-02-21 05:19:00". Do you which function i can use to derterminate the difference in time between this value and an other one. For exemple: this one : 2007-02-21 05:19:00 and this one : 2007-02-20 14:21:53 Thanks a lot, Karine H. _________________________________________________________________ [[elided Hotmail spam]] [[alternative HTML version deleted]] ______________________________________________ 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.
