clplot allows one to highlight the regions of a curve or dataset which fall into different ranges such as quantiles or critical performance levels. Unlike cheap imitations :-), clplot changes colors at exactly the range limits selected, rather than at the next actual data point. The latest version allows for multiple plots on the same graph.
Note: this is a clean, but not optimal implementation. See "clplot.r" in the Plotrix R-packagae for a better, but more complicated version (disclaimer: I wrote that as well).

Version Published Release Notes
2.1.0.0

Vsn 2.1: clplot now returns the cut-values and the colormap used. This allows the user to plot a second curve on the same graph by feeding these outputs into the next function call. Also minor bugfixes
2.0.1.0

Revision 2: improved input checking; fixed scaling bug that prevented large colormaps (e.g. 'jet', 'hsv' ) from properly scaling to range of y-values.
2.0.0.0

Revision 2: improved input checking; fixed scaling bug that prevented large colormaps (e.g. 'jet', 'hsv' ) from properly scaling to range of y-values.
