Usage
fun(x, digits)

|
| digits |
arguments for the round and signif functions.

Details
This is a group method for the functions of the Math group
(sin(), log(), round(), and so on),
which are essentially all functions that return a one-to-one
numerical transformation of their (numeric) argument.
This method usually results in an error unless all the variables in
the data frame are numeric vectors or numeric matrices.
Value
returns a data frame, each variable of which is transformed by the
function, fun.
