If you are happy with the character strings printed out then you can use
the capture.output function.
If you want the numbers (without needing to convert) then look at the print
method for the class of object that you are working with and see what the
code is. It is probably calling another function to produce the output and
you could just call that function directly. If not, you can copy that
section of the code into your own function to call and have it return the
object rather than printing.
