Hi, I was wanting to get the diagonal of an openmx output matrix and tried "diag()" as shown below with the matrix.

Question: should (can?) we overload "standard" R functions, or is there to be an mxDiag() equivalent?

If the latter, it would be nice if where possible it worked (to parameters) as the {base} library functions do.

I guess that it would be VERY helpful if code like

a = mxRun(factorModel) round(diag(a$S), 2) # worked, i.e, output a matrix rounded to 2 decimal places

> diag(a$S) Error in y[1L + 0L:(m - 1L) * (n + 1L)] a$S SymmMatrix 'S' Labels matrix: No labels assigned.
