I see that you are referring to an illustration produced by an example on a help page. In this illustration the transformation of value to color begins with red at the minimum and traverses the red-blue range with increasing values. Let us say that your values are contained in a vector named "values". values<-sort(runif(10)) plot(1:10,pch=19,col=color.scale(values,extremes=c("blue","red"))) Jim
