Thank you Deepayan for your reply.
Using your example, I was able to get bars in greyscale that separates
nicelly in Black and white. However, I cannot get the key to do the
same. All I can do, using hte col argument of
simpleKey, is to get the legend text to shade go through all the grey
scales, with color boxes
by the text.
col = gray.colors(10)
