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

Hello,

I recently submitted a package for consideration in CRAN. One of the
comments was:

Please ensure that you do not use more than 2 cores in your examples.

I do not believe my package does this. Is this a general comment for a
package that requires doParallel or was this triggered because one of my
examples actually used more than 2 cores?

Thanks
John

The latter. In examples, vignettes and tests you must not start more 
than 2 workers as resources for CRAN checks are limited.

Best,

Thanks Uwe,

Is there a way to find out on my end where this is happening?

Thanks
john

Yes, simply set the env var
_R_CHECK_LIMIT_CORES_=true
to reproduce.

Best,
Uwe

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
