Dear List, I have a column of dates say: test$date1 <- seq(19900511, to = 19900521)
I want the next column to have the number of days between each subsequent date i.e days between r(i+1) and r(i) Any easy way to do this? (I've done it in a roundabout way but just wondering if there is any way more than done a loop) Thanks. ______________________________________________ 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.
