I wrote this code in R, in order to plot a density function kernel smoothing and then save the plot as a "eps" file: library(ks) library(rgl) kern <-read.table(file.choose(),sep=",") hat <-kde(kern) plot(hat,drawpoints=TRUE,xlab ="x",ylab="y",zlab="z") rgl.postscript("plot1.eps","eps",drawText=TRUE) The problem is that when I insert that eps file in Latex, the colors of the plot are not the same as the plot which is generated in R and it just shows the plot in one color (yellow) instead of a rage of colors (yellow, orange, red...) which shows different densities...
