How to scale a object to 120%?

[namiwang]

I've got an object by:

planeWall = new THREE.Mesh(new THREE.PlaneGeometry(10,5,1,1), material);

Then I want to make it bigger, say, 20%
so I tried:

planeWall.geometry = new THREE.PlaneGeometry(12,6,1,1);

but failed,debugger says:

TypeError: Cannot read property 'radius' of null

Is there anyone has some experience for this?

planeWall.scale.set(12,6,1);

thanks,got it,
but it should be plane.scale.set(1.2,1.2,1), right?

@JacobBovatsek's solution would imply having new THREE.PlaneGeometry(1,1,1,1).

why not work ? planeWall.scale.set(-5,-5,-5);

@tmdeft three.js does not support negative scale factors. See http://stackoverflow.com/search?q=%5Bthree.js%5D+support+negative+scale
