Dear R People: I am using Response Surface Models and and also using the "persp" function to plot them. Today my particular model is y~ x1 + x2 + x3 I can fit my RSM easily. My question is: how do I use the persp such that I can fix the x3 at a particular value, please? > smell.code <- coded.

Re: [R] persp() problem

Your call to persp() is fine, and works just fine for me. Obviously there is something funny about your data (x, y, and z). They must not be numeric (despite appearances). There is something you haven't told us here; how did you obtain/construct x, y, and z? Try the following: x <- y <- 5*(0:

This wiki page has the answer. Draw the plot first to establish the coordinate system and create the viewing transformation matrix. Draw the grid lines with lines(trans3d()), and then put a: par(new=T) ... and then redraw the plot over the gridlines.
