Extract or replace the diagonal of a matrix, or construct a diagonal matrix.

A dibble if x is a dibble. See base::diag() for the return values
of the default methods.
A dibble, matrix, vector or 1D array, or missing.
Unused, for extensibility.
Optional dimensions for the result when x is not a matrix.
(When x is a matrix) logical indicating if the resulting vector, the diagonal of x, should inherit names from dimnames(x) if available.
A character vector of axes.
Replacement values.
These functions override base functions to make them generic. The default methods call the base versions.
