There are (very simplistic) group methods (see, e.g., Arith)

Arith
signature(e1 = "dMatrix", e2 = "dMatrix"): ...
Arith
signature(e1 = "dMatrix", e2 = "numeric"): ...
Arith
signature(e1 = "numeric", e2 = "dMatrix"): ...
Math
signature(x = "dMatrix"): ...
Math2
signature(x = "dMatrix", digits = "numeric"): ...
