Hi List, I want to show three matrices in a 3D plot, one horizontal, and the other two as vertical slices. Ideally this would use the persp or drape.plot functions. I have found a means of assigning one matrix to the lower xy plane (like a carpet), thus: mat_2D <- matrix(runif(100),nrow=10,ncol=10) drape.plot( c(1:10),c(1:10),mat_2D, zlim=c(0,1000),z2=log10(mat_2D)) However, this still leaves 2 remaining; I would like to draw these as vertical slices, on the xy and yz planes (like wallpaper). Any ideas? Thanks! Tom -- View this message in context: http://r.789695.n4.nabble.com/vertical-slices-in-persp-or-drape-plot-tp4646595.html Sent from the R help mailing list archive at Nabble.com.
