luded in my last post filled this gap. If Matrix::band
and Matrix::bandSparse can set/get bands in this way, I would like to
see how this can be done. If not, then perhaps they could be extended to
achieve this functionality.

Dear R developers,
I was looking for a function analogous to base::diag() for getting and
setting bands of a matrix. The closest I could find was Matrix::band(),
but this was not exactly what I wanted for two reasons. Firstly,
Matrix::band() returns a matrix rather than just the specified band
