[R-pkg-devel] Number of cores in examples

[John Harrold]

Howdy Folks,

I'm testing this on R-hub, and I've set option in the environment. I put
links to the Windows and Ubuntu outputs below. I've searched for the
obvious (core, parallel, etc), but I'm not really sure what I need to look
for to indicate that more than one core is being used. If someone could
point it out to me I'd be very grateful.

Thanks
John
