I have a data frame of 3 vectors (x, y and z) and would like to
transform this so that I could use persp. Presently I have y-level
copies of each x level, and a z value for
a strategy for this that I use is just
persp(interp(x,y,z))
where interp is from the Akima package, and x,y,z are all
of the same length.
