useR's,
I want to be able to rotate a matrix 90 degrees, clockwise. For example,
> mat
[,1] [,2] [,3]
[,1] 1 2 1
[,2] 3 2 6
[,3] 4 5 3
I want to rotate it, so that it looks like this...
[,1] [,2] [,3]
[,1] 4 3 1
[,2] 5 2 2
[,3] 3 6 1
Does anyone know a quick and straightforward way to do this?
Thanks in advance.
