Question: changecoords command changes with(plots)

So here's a problem.  We have two of the same commands that operate differently in and outside the plots package. 

changecoords([x, y, z], [x, y, z], spherical, [r, theta, phi])
                        [r*sin(phi)*cos(theta), r*sin(phi)*sin(theta), r*cos(phi)]
with(plots):
changecoords([x, y, z], [x, y, z], spherical, [r, theta, phi])
Error, (in plots/changecoords) changecoords does not accept plot options or other additional arguments

How can we get around that problem?
