[R] Row percentages for a table object

I an stumbling on something that is probably very simple, but I cannot see the solution. I have an object generated by the table () function and want to recompute this table so each cell represents the percentage of the corresponding row sum.

Of course a dedicated function can be written (which I have done), containing the necessary loops etc., but there should be a simpler way. I'd prefer something simple and as transparent as possible since it is for use in a text I am writing for my students. I have fiddled around with the apply () function but have so far been unable to find something that works.

Any suggestions?

Tom
