I am trying to upload a new version of the reclin2 package, but it fails
the pre-tests on Debian with the following message:
> * checking examples ... [14s/4s] NOTE
> Examples with CPU time > 2.5 times elapsed time
> user system elapsed ratio
> select_threshold 3.700 0.122 0.455 8.400
> select_n_to_m 4.228 0.180 0.623 7.075
> * checking for unstated dependencies in ‘tests’ ... OK
See
https://win-builder.r-project.org/incoming_pretest/reclin2_0.3.1_20230716_124651/Debian/00check.log
for the complete output.
I can't see why this happens and I can't seem to reproduce this on my
machine. The examples do call makeCluster from parallel, but only start
one thread. The code that is ran in the examples only call base-r
functions and data.table functions. I can imagine data.table starting
multiple threads. However the example consists only of 17 records; and
data.table should not use more than two threads on that system anyway.
So I don't see where the large difference between the two is coming
from. Does anyone have a clue?
The code is here: https://github.com/djvanderlaan/reclin2 one of the
examples that fails is here:

Thanks.
