It depends on structure of your data (unstated). If I presume that you have data frame and you have date in some column you can just use standard subsetting new.data <- your.data[your.data$Date > some.threshold.Date, ] Regards Petr > > > > -- > View this message in context: http://r.789695.n4.nabble.com/deleting- > data-of-a-given-date-range-tp4651272.html > Sent from the R help mailing list archive at Nabble.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. ______________________________________________ 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.
