Dear All:
It seems a very silly question. But I never tried it before. I am teaching a college algebra class this summer.
I need some help with graphing intervals on the real line. For examples:
{x | -7<= x < 5 and x > 7}
{x | x > 3}
etc...
Check out the intervals packages: library(intervals) example(plot.Intervals) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com
