What you are constructing here is a function that maps value to colour, but keeping it as breaks and cut values and colours instead of representing it as a function. Wouldn't it be nicer to build a real function object and have that to pass around? ggplot uses a different approach, for example in ?scale_fill_gradient, but ggplot uses "+" to add the layer objects together to create a plot. Nice. ggplot does things pretty well. Perhaps if we scrap all the other graphics systems.... :) Barry ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
