Hi All, I am looking for a color palette like this: http://www.ncl.ucar.edu/Applications/Images/h_long_5_lg.png I think I found out how some time ago (something like Colors[1:n]), but when I now wanna use it, I could not remember how I did it. Does anyone know which package I could use?
Hi Linda, You can do it with color.legend in plotrix. plot(1:10) color.legend(1,8,7,8.5,align="rb", rect.col=color.scale(1:21,c(0,1,0.5),c(0,1,0),c(0.5,1,0)), legend=seq(-50,50,by=10)) Jim
