Thanks Jim. After installing plotrix I still had a bit of trouble getting this to work and I don't (yet) know enough R to fix it:

> speedoplot(0.5,5,5,2,"Speedoplot")

Error in polygon(xv, yv, border = border, col = col, lty = lty, lwd = lwd) : has not been called yet

But the error went away if I plotted something else first.

Also the colour bands are skewed - but that may just be a side-effect of my other plot.

Sounds interesting, but probably a bit overkill at this stage.

Thanks again for coding up the dial!
