R help - Oct 2011 - Background Colors

Hi R-Help -

If I make a plot:

numYears = 500
plot(x = c(1,numYears), y = c(200,300), xlab = "Time", ylab =
"Vegetation
Class", xlim = c(100,600), ylim = c(200,300), type="n")

Is there a way to make different parts of the background for the plot
different colors?

For example, I'd like to have the background color col = (250,250,0,50) for
y = c(200,204), and col = (250,125,0,50) for y = c(210,212).

Any suggestions?

Thanks in advance for the help,

Gabe

Hi,

Yes, one way to do that is by using function polygon().
