Try this: format(down.215$time, "%H:%M:%S") On Tue, Jul 15, 2008 at 4:50 PM, stephen sefick <ssefick at gmail.com> wrote:> RM215.sp <- SpatialPoints(RM215, proj4string=CRS("+proj=longlat > +datum=WGS84")) > d060101 <- as.POSIXct("2006-01-01", tz="EST") > study_seq <- seq(from=d060101, length.out=761, by="days") > up.215 <- sunriset(RM215.sp, study_seq, direction="sunrise", > POSIXct.out=TRUE) > down.215 <- sunriset(RM215.sp, study_seq, direction="sunset", > POSIXct.out=TRUE) > > #I would like to extract just the time part of the output is there any way > to do this? > > -- > Let's not spend our time and resources thinking about things that are so > little or so large that all they really do for us is puff us up and make us > feel like gods.
