[R] x y plot with z coordinate scaling to a color value

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


and then using color.legend() from plotrix to add a colorbar. Is there anything where I can just call (for example)


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.

Thanks for your help!
