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:

of y is the number of columns of z,
You should also name the rows and columns in z with x and y
