Hi all,
I'd like to plot the Real and Imaginary parts of some f(z) as two
different surfaces in wireframe (the row/column axes are the real and
imag axes). 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? I
envision, for a matrix of complex values zmat, pseudocode:
wireframe(c(Re(zmat),Im(zmat), groups=1:2)
-- and yes, I'm fully aware that without a connection between the
'groups' variable and zmat, this won't work as written.
All suggestions (including "read the help file for {some lattice func I
didn't know about} ) greatfully accepted.
Carl
