In R, I am trying to implement matrices as arguments in functions to return another matrix with the result being certain matrix elements modified.

In R, can you create a function 'double_odd' of which argument is an integer matrix x returning a matrix same size as x with all its odd numbers doubled.

A basic solution would be appreciated as it'd help me understand the language more, however, seeing a short version would be interesting to see as well.

Many thanks in advance.
