[R-pkg-devel] error in sample(), invalid 'size' argument

[Roberts, David]

Thanks Iñaki.  I was unaware of rhub.  Nice tool!  Unfortunately, their 
debian machine odes not reproduce the error.  I have written the R 
Submission crew to see if I can submit a package with a 
print(str(mss.10)) call to see the output in the examples log, or if 
that is an abuse of CRAN submission.  We'll see what they say.

Thanks again for your help, Dave
