Subject: negative and positive values in diff. colors
Hi R-users,
I have a set of elevation residuals as geodata points. I would like to
display them in the following way:
-negative values using pch=20 (filled circle)
-positive values using pch=1 (empty circle)
while using the cex.max=5, cex.min=0.1 for points() to represent the
residuals value. Basically I would like to distinguish neagtive and
positive values at my map. How to do this.
Thanks in advance,
Rado
