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

Hello Max,

The comment I received was:

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

I believe the only output I received was these incoming pretest results:

https://win-builder.r-project.org/incoming_pretest/ubiquity_1.0.0_20190821_023712/

Feel free to browse through them.

Thanks
John

Hi John,


 From the R-hub output you shared with us, we can see that you don't get
the error on Ubuntu with R-devel, nor on Windows with R-3.6.1. When you
received the original email from CRAN with the check output, on which
platform did you get the error about using too many cores? Perhaps that
info could help narrow it down, or at least you would know on which
platform to test.

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 Uwe,

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

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

Best,
Uwe

Thanks

     The latter. In examples, vignettes and tests you must not start

more

     than 2 workers as resources for CRAN checks are limited.
