Might be a little easier to use panel.3dpolygon from latticeExtra. (or not) e.g. something like wireframe(volcano, drape = TRUE, scales = list(arrows = FALSE), panel.3d.wireframe = function(x,y,z,...) { panel.3dwire(x,y,z,...) panel.3dpolygon(x = rep(pretty(x), each = 3), y = min(y), z = c(range(z),NA), ..., border="grey", lwd=2) }) > >> >> Many thanks >> >> John >> >> >> --- On Thu, 4/8/10, David Winsemius <dwinsem...@comcast.net> wrote: >> >>> From: David Winsemius <dwinsem...@comcast.net> >>> Subject: Re: [R] 3-D response surface using wireframe() >>> To: "array chip" <arrayprof...@yahoo.com> >>> Cc: r-help@r-project.org >>> Date: Thursday, April 8, 2010, 3:46 PM >>> >>> On Apr 8, 2010, at 3:13 PM, array chip wrote: >>> >>>> David, >>>> >>>> That does the job!
