Extract or replace the diagonal of a matrix, or construct a diagonal matrix with the same behaviors as
diag prior to R-3.0.0.
A matrix, vector or 1D array, or missing.
Optional dimensions (
Either a single value or a vector of length equal to that
of the current diagonal. Should be of a mode which can be coerced

Started from R-3.0.0,
diag(x) returns a numeric matrix with NA in the
diagonals when x is a character vector. Although this follows what the manual says, this
breaks the metaSEM. The
Diag has the same functions as
diag except that
Diag(x) works for a character vector of
x by returning a square matrix of character "0" with
x as the
