Re: [R] ColorRamp different from ColorRampPalette

Try the rgb function in the grDevices library. pal.cr<-colorRamp( c("blue", "white", "red"), space = "rgb") plot(rep(0,40),pch=16,col=rgb(pal.cr((0:40)/40),max=255)) Troy -- View this message in context: http://n4.nabble.com/ColorRamp-different-from-ColorRampPalette-tp889372p1692642.html S

Look at the output of pal.cr((0:40)/40) Hadley On Fri, Apr 17, 2009 at 2:42 PM, Etienne B. Racine wrote: > > I try to use ColorRamp as ColorRampPalette (i.e. with the same gradient), but > it seems there is a nuance that I've missed. > > pal.crp<-colorRampPalette( c("blue", "white", "red"), space

[R] ColorRamp different from ColorRampPalette

I try to use ColorRamp as ColorRampPalette (i.e. with the same gradient), but it seems there is a nuance that I've missed. pal.crp<-colorRampPalette( c("blue", "white", "red"), space = "rgb") plot(rep(0,40),pch=16,col=pal.crp(40)) # is great But, using the same gradient with colorRamp is giving
