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

[Uwe Ligges]

The message came from a CRAN team member, so please ask the CRAN team 
member who found that issue if you cannot work it out. Readers of this 
list cannot help unless reading the sources of your package that you 
have not shared with the list.

Note that CRAN team members may also make mistakes given there are 
dozens of new submissions on a single day.

Best,
Uwe Ligges
