Objet : [R] image.plot specify colors for range of data points, please help
Hi
If I had a dataset of the following below and I want to plot colors for this
image.plot so that:
red for data above 1
black for data between/equal 1 and -1
green for data below -1
normally its:
image.plot(data) but how do I add the colors for the range of data points as
above?
Many thanks for your help!
