This converts the input to a "yearmon" class object which represents the date as just a year and month. We then convert it back to "Date" class using the frac argument to indicate whether the first or last of the month is to be used. Finally we paste the time to it which also converts it to character. library(zoo) d <- "2012-09-27" ym <- as.yearmon(d) StartDt <- paste(as.Date(ym, frac = 0), "00:00:01") EndDt <- paste(as.Date(ym, frac = 1), "23:59:59") -- 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.
