[R] R matrix help

[Jeff Newmiller]

What makes you think that with 12 elements the dimensions should be 3x4? It seems that 4x3 would be equally valid.

In every use of matrices that I have encountered, the dimensions have been relatable to some known quantity from the problem context, and matrix dimensioning has been an exercise in consistency checking rather than a guessing game. I recommend that you look at your overall problem again.
