Question from an [R] novice... Hi, I have a vector of date/times like the one shown below (a truncated sample of a much longer list...)
> dates[1:4] [1] "2006-03-16 08:41:00" "2006-03-16 10:28:00" "2006-03-16 11:03:00" [4] "2006-03-16 11:04:00" I would like to generate a weekday histogram showing the frequency of dates falling on each weekday. I know that the function weekdays() gives me the weekday for each date in my vector, but the hist() function can't plot non-numeric values. There should be a function to allow me to do this simply. Any thoughts? After having done this, I would also like to bin my histogram in 12 hr periods (Mon 7am - 7pm; Mon 7pm - Tues 7am; Tues 7am - 7pm; Tues 7pm-Wed 7am... etc) so that I can plot the frequency of event occurrences within each 12 hour period over the course of a week. Any help would be greatly appreciated.
