Team, we figured this out, Roger at XLSOLUTIONS solved the puzzle for us..!! Okay you can easily change the color palette.
see below: library(MASS) library(deldir) set.seed(1123) y <- runif(20) x <- runif(20) #run voronoi from deldir package ddd <- deldir(x,y) ttt <- tile.list(ddd) plot.deldir(ddd,wlines="tess") #play with colors *ccc <- colors()[1:20] or ccc <-heat.colors(20) or ccc <-terrain.colors(20)* plot(ttt,polycol=ccc,close=T) Rolf Turner wrote: > > On 12/08/2007, at 1:22 PM, zubin wrote: > >> Hello! >> >> I am using the deldir package to visualize my data, pretty neat. >> However, i need to fill the colors using polycol =, fill with colors >> like a heatmap - more of a gradient fill.
