Hi all I'm trying to create a three-dimensional wireframe-type plot, much like the screenshot shown at http://www.r-project.org/screenshots/volcano-persp.jpg In my case, I'm trying to show a density estimate of two-variable system, using the GenKern package. I've used the image() and contour() to create a nice shaded plot, but I've found a 3d plot is often easier for the audience to absorb. The session is simple enough; dfw is a data.frame of two variables, pressure and flow.> library(GenKern) > attach(dfw) > ks<- KernSur(pressure,flow)#now, make the shaded contour plot.> image(ks$xvals,ks$yvals,ks$zden,col=terrain.colors(100), axes=TRUE) > contour(ks$xvals,ks$yvals,ks$zden,add=TRUE)Any ideas from here?
