Hello R List -
I have to import Excel files (either as .csv files or using RODBC) into
R (2.4.1, Windows) and operate on dates and times (e.g. find minutes
between times, change dates to days of week or analyze by weeks of
year). The help files for format.Date, strptime, as.POSIX,
DateTimeClasses, etc. etc. are informative but perhaps a little terse.
I have googled unsuccessfully for a more general description of how R
represents times and dates, and the methods (e.g. date arithmetic) for
working with them. Can a reader point out such an introduction,
preferably on-line?
Thank you,
Ben Fairbank
