Hi! Is not there an standard R function to retrieve the day of the year (since 1st Jan of the same year)? I know I can make my own using julian, but find it weird that having days(), months() etc doy() does not exist as an standard function.
Also, is the following not a bit inconsistent? > a <- chron("20100506",format="ymd") > a [1] 100506 > years(a) [1] 2010 Levels: 2010 but instead have to cast to Date to apply julian: > julian(a) Error in names(d) : 'd' is missing > julian(as.Date(a)) [1] 14735 attr(,"origin") [1] "1970-01-01" Thanks Agus -- -- Dr. Agustin Lobo Institut de Ciencies de la Terra "Jaume Almera" (CSIC) Lluis Sole Sabaris s/n 08028 Barcelona Spain Tel. 34 934095410 Fax. 34 934110012 e-mail agustin.l...@ictja.csic.es https://sites.google.com/site/aloboaleu/ ______________________________________________ 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.
