I can draw the polygon as above, but I don't know how to do the
coloring. It is easy to give the polygon only one color (e.g. through
polygon(c(x1,x2),c(y1,y2), col="red")), but I need a way in which to
color the polygon such that the color moves through the color spectrum
from red (left) to green (right).
Can anyone help me to achieve this?
I don't know of another way than to segment the polygon and give the
segments distinctive colours. The function rainbow(n, start=0, end=1/3)
might help specifying the colours, where n is chosen sufficiently high.
