I want to plot a large number of line segments, with a color associated with each line segment (I'm actually plotting a function of the edges of a 2d graph, and I want to use color to indicate the level of the function.) I originally thought I could use lines, but lines puts all its lines in one color (from help(lines), "col: color to use. This can be vector of length greater than one, but only the first value will be used.").

Is there a function that does what I want? Right now I'm using the obvious solution of calling lines in a loop with a single segment, but this is really quite slow for my purposes, as I have several thousand lines total to plot.

Cheers,

rif
