Hi,
I have a data set of points which are represented by 3 variables x,y,z where
x is the position of the point on the x-absciss and y on the y-absciss. Each
of my points has a value z, which I want to be displayed as follows: the
more z is high, the more the color on the map is dark.
How can I achieve this ?
Hi Babaorumi,
Have a look at the example for the color.scale function in the plotrix
package.
