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. The only colors i get are very blocky - how do i assign the correct colors for a gradient, even a grayscale? i tried the chart of R colors, using 200 numbers for grayscale but not getting them. The polycol = colors the cells in the tesselation with the value a specific vector for color.
Code below: library(deldir) set.seed(1) #generate data y <- runif(20) x <- runif(20) z <- rep((2:4),2) #run voronoi from deldir package ddd <- deldir(x,y) ttt <- tile.list(ddd) plot.deldir(ddd,wlines="tess") #play with colors plot(ttt,polycol=z,close=TRUE) ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
