Are there any packages which offer functions to do so?Would the subset argument to wireframe help? e.g. wireframe(z ~ x*y, subset= (z > 50)) Cheers Jason -- Indigo Industrial Controls Ltd. 64-21-343-545 jasont at indigoindustrial.co.nz -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

I have a response surface model (z ~ x*y) which is displayed as a trellis wireframe plot. I wish to cut the surface at various linear planes in the z axis (e.g. z = 50, etc.). Are there any packages which offer functions to do so?

Are there any packages which offer functions to do so? Sounds a lot like a job for contour to me. Contours are more readable than wireframes anyway. -- Patrick Connolly HortResearch Mt Albert Auckland New Zealand Ph: +64-9 815 4200 x 7188 ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~ I have the world`s largest collection of seashells.
