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? Many thanks! Linda [[alternative HTML version deleted]]
see if this is what you need:
require(lattice)
x <- matrix(1:100,10)
levelplot(x,col.regions=colorRampPalette(c('dark
red','white','dark blue')))
