I've never much worked with dates and times, but find that I must now do
so. I'm doing some very basic EDA and using the GUI to generate some
plots. When making plots using the GUI, how do I control the span of the
date axis? I'm aware that S-Plus encodes the date in a manner similar to
unix/linux, but I don't know how to define things like tic marks in
terms of, say hours. For example, if I want a tic mark every hour, how
do I declare that? Using command line plots, how would I subset the data
such that I plotted only data between, say, 11/29/2007 14:15:00 and
11/29/2007 18:15:00?
All data are currently in a data.frame and the data type for the dates
column is timeDate.
I'm using S-Plus 7.0.6 under Windows XP.
