I can put a legend on a plot with something like:
legend('bottom', leg.txt, horiz = TRUE, fill = colors)
But what if the arrays leg.txt and colors are too big? I would still like to
provide a legend but to save space I would like to just show small boxes
with the color filled in so it will still fit on the plot. If I could adjust
the size of the boxes (at least in one dimension) that would be desirable.
As a bonus and if there is room I would like to label the top and bottom
(left and right) of the legend with text indicating a minimum and maximum. I
am relatively new to 'R' and especially 'R' graphics so any help
would be
greatly appreciated.
Thank you.

Try something like this:
legend('bottom', leg.txt, horiz = TRUE, cex=.75)
A workable example is requested and would have been helpful.
