Hello! I am trying to identify which ones of a vector of dates are US holidays. And, ideally, which is which. And I do not know (a-priori) which dates those should be. I have, for example: x<-seq(as.Date("2011-01-01"),as.Date("2011-12-31"),by="day") (x)
I think chron should help me here - but maybe I am not using it properly: library(chron) is.holiday(chron) # Says that none of those dates are holidays ?is.holiday says: "holidays" is an object that should be listing holidays. But I want to figure out which of my dates are US holidays and don't want to provide a list of Package timeDate does almost what I need: library(timeDate) holidayNYSE(2008:2010) holidayNYSE() However, I don't need all the NYSE holidays (like Good Friday). Just the major US holidays - New Years, MLK, Memorial Day, Independence Day, Labor Day, Halloween, Thanksgiving, Christmas. Is there any way to identify major US holidays? Thanks a lot! - Dimitri Liakhovitski marketfusionanalytics.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.
