[R] Representing a statistic as a colour on a 2d plot

[mister_bluesman]

Ive been getting the color.scale function to work. However, I really need to
know is that if i have values: 0.1 0.2, 0.3, 0.4, 0.5, for example, how I
can plot these using colours that would be different if the contents of the
file were 0.6, 0.7, 0.8, 0.9 and 1.0. Using color.scale scales them so that
they differ, but only relative to each other, rather than taking the actual
value and converting them to some unique colour/colour intensity.

Many thanks
