Hi, I have the following string that I converted to a POSIXct:> a <- "2009-08-24 10:00:00.213" > a.p <- strptime(a,"%Y-%m-%d %H:%M:%OS") > as.double(as.POSIXct(a.p))[1] 1251122400 I can't seem to get the decimal fraction of .213 out by casting to double or numeric. Is there anyway to make sure that POSIXct spits that out? Thank you. adschai

Thank you.It is in the object, just rounded when printed to the console, see: format(as.double(as.POSIXct(a.p)), digits=22) Best, Uwe Ligges> adschai > > ______________________________________________ > R-help at 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.
Try this:> options(digits = 20) > as.double(as.POSIXct(a.p))[1] 1251122400.213 On Sat, Aug 29, 2009 at 11:37 PM, R_help Help<rhelpacc at gmail.com> wrote:> Hi, > > I have the following string that I converted to a POSIXct: > >> a <- "2009-08-24 10:00:00.213" >> a.p <- strptime(a,"%Y-%m-%d %H:%M:%OS") >> as.double(as.POSIXct(a.p)) > [1] 1251122400 > > I can't seem to get the decimal fraction of .213 out by casting to > double or numeric.
