firts date 2011-01-01 2011-01-02 2011-01-03 2011-01-04 2011-01-05 * * * A 2011-02-03 0 0 0 0 0 * * * B 2011-01-02 0 10 11 12 13 * * * C 2011-04-02 0 0 11 12 13 * * * D 2011-02-02 0 0 0 0 0 * * * E 2011-11-02 0 0 0 0 0 * * * * * * I have this "annual productivity data(2011)" and I need to convert this as "D-Day data". That is to say, I need this form. firts date D-DAY D+1 D+2 D+3 D+4 * * * A 2011-02-03 0 0 0 0 0 * * * B 2011-01-02 0 10 11 12 13 * * * C 2011-04-02 0 0 11 12 13 * * * D 2011-02-02 0 0 0 0 0 * * * E 2011-11-02 0 0 0 0 0 * * * * * * D-day is the "first date" and each cells are day-productivity of the day. how can I make a code for that? -- View this message in context: http://r.789695.n4.nabble.com/macro-function-tp4427385p4428131.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.
