Dears,
before I start programming my own function I would like to ask you whether
there is any function already available that lets me plot a x/y plot with the
colors of the points determined by scaling a third variable z into a defined
colorramp?
Until now I am using a wild combination of functions to create a colorvector by
hand, then calling
plot(x,y,col=colors)
and then using color.legend() from plotrix to add a colorbar. Is there anything
where I can just call (for example)
plot(x,y,z)
and get a plot and a colorbar next to it?
If not I have to program that myself because my current way involves a lot of
steps and readjusting plotting regions.
Hi Jannis,
Have a look at the example for color.scale in the plotrix package, and
you already know about color.legend.
Jim
