Prof. Ripley has provided very helpful information regarding X-axis labeling with POSIXct-class dates. Now I've run into another bit of problematic behavior. I'm running R 1.3.0 on Windows NT 4.0. When I create a plot with the optional argument xaxt = "n", and the X axis is generated from dates of class POSIXct, the X axis is plotted. Obviously, I'd like to prevent the X axis from being plotted so that I can create a tailored X axis for plotting. I have a work-around for the moment: plot without any axes, then add each axis with a separate "axis" statement. But perhaps there is a way to get the desired behavior in the first place? Incidentally, I can't check documentation for R 1.3.1 because, due to my company's slow and extremely conservative response to the Nimda worm, I can't access the web (I now realize how much I use it!). Apologies in advance if the latest R version has already handled this.

The author could have anticipated that you might want to do it, I guess! I'll write a more sophisticated version of plot and axis for POSIXt classes for 1.4.0: what is there was intended to be a quick hack to encourage migration from chron classes.
Incidentally, I can't check documentation for R 1.3.1 because, due to my company's slow and extremely conservative response to the Nimda worm, I can't access the web (I now realize how much I use it!). Apologies in advance if the latest R version has already handled this.
I suppose you can't upgrade R either, then? We would encourage people to go to 1.3.1: it had a lot of bug fixes, and we do not anticipate any further releases before 1.4.0 which `is not yet scheduled, but is likely to be around the end of 2001.'
