Hello, I'm trying to overlap a contour and a filled.contour: as I read in a previous post this can be done calling contour() in the plot.axes of filled.contour. When I do it (see example below) the contour is placed instead of the color bar, while the filled.contour is not drawn at all, which is the right way? Thanks Andrea postscript("covtd.xy.eps", width=6.5, height=5.5, horizontal=FALSE, onefile=FALSE, paper = "special") filled.contour(plot.axes={ contour(seq(1,nlev),seq(1,nlev),real2) }, seq(1,nlev),seq(1,nlev),real2,levels=c(-40,-20,-15,-10,-7.5,-5,-2.5,-1.5,-0.5,0.5,1.5,2.5,5,7.5,10,15,20,40),xlab="Model levels",ylab="Model levels", color = colorRampPalette(c("blue", "white", "red")),main=expression(paste("Unit: ",10^-6," ",K%.%s^-1))) dev.off()
