Call plot() with xaxt="n", then call axis() to add the labels you want. You can use plot.POSIXct as a model. > I can kind of have R lable the bottom by chaning my plot to "plot(usr.cpu > ~ Time), yet then the graphs take much, much longer to generate. I presume that Time is a character variable, so a lot of conversion is goin on: but we are short on details here. > Worst case, I will use "plot(usr.cpu ~ Time)" - yet, anyone know why this > would take a very, very long time? -- Brian D.
