Hi all,
I've got a simple 3D plot as follows...
> xx <- seq(-20,20,.5)
> yy <- seq(-20,20,.5)
> zFunc <- function(x,y){3*x^2*y}
> z <- outer(xx,yy,zFunc)
> persp(xx,yy,z,theta=30,phi=30,ticktype="detailed")
Just beautiful!
My question is how do I constrain the plot to only display x^2 <= y <= 1?
Thanks in advance,
Nick
