Dear list
I'm having trouble with inverting color gradation.
As seen in the "rgl" example,
library(rgl)
example(rgl.surface)
I understand that I can assign colors to heights for each point.
col <- colorlut[ y-ylim[1]+1 ] # assign colors to heights for each
point
However, I am now trying to assign inverted colors.
(top colored green, and bottom colored gray).
Is there any way that I can do this?
