Thank you! That bit about "Re(z) + Im(z)" was what I missed.

I know I can do it by, roughly speaking, something like plotz<- expand.grid(x={range of Re(z)}, y={range of Im(z), groups=1:2) plotz$func<-c(Re(f(z),Im(f(z)) wireframe(func~x*y,data=plotz,groups=groups) But that seems like a clunky way to go, especially if I happen to have started out with a nice matrix of the f(z) values. So, is there some simpler way to write the formula in wireframe? IThis is reasonably simple: fz<- matrix(complex(real = 1:100, imaginary = 101:200), 10, 10) zr<- as.vector(row(fz)) zc<- as.vector(row(fz)) wireframe(Re(fz) + Im(fz) ~ zr + zc) The as.vector() are needed because matrix x and y in the formula have a special meaning. -Deepayan
