The short answer is you can't, at least not easily. The computation is 
done at the C level, and all that is returned are the p-values.

You could always download the sources and modify the C code to return 
the statistics as well, but that is only feasible if you know C.

Alternatively, you could code up the mas5calls using R, but the 
description of how they are computed might not be 100% clear, so you 
might not be able to get the same exact values.
