3D surface plot from 2D matrix

Question

Using a 2d matrix in R, how can I create a 3d surface plot, where columns=x, rows=y and the values are the heights in z?

In the example below, x values would be 1:5,

Answer 1

To get a 3D surface plot of a 2D matrix that contains the Z-values, try:

require(plot3D)

persp3D(z = TheMatrix2D, theta = 120)

Use theta to adjust the viewing angle. With my data, I get the following plot:
