Furthermore its importance is that it recommended a viable approach to using date/time classes which avoids many problems that could otherwise wind up wasting large amounts of time through inappropriate use of those classes. The second problem that it addresses is that using the date time classes can be tricky and it gives a table of idioms that can be used straight away to do many common date time manipulations. I personally faced these problems in earlier days of R and decided to contribute this so that others would have an easier time of it and not have to waste the time I did on simple date/time problems. I think it was successful in that regard as postings about date/time problems sharply fell off in the r-help list after it was published. Since that article many improvements in R have been made yet the main points and most or all of the detail still remain valid and useful. -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.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.
