Hi Ben,

Thanks for the response.  I'm sorry I didn't give you the heads up about
r-forge.  I messed around with 'nboot' and 'npermut' by decreasing from
their defaults of 1000 to 10 and that allowed me to run it just fine.  In
general, what is the harm in straying away from these default parameters?

Jacob
