Dear all,
Hope you are well! Recently, in the check before a re-submission, I
got an unexpected note when doing R CMD Check using
rhub::check_for_cran(), saying that "Examples with CPU (user + system)
or elapsed time > 5s".
I didn't expect this note to appear because the same examples didn't
cause this note in the previous submission last December. Compared
with the previous submission, we only edited documentation, there was
no change in the R code for functions of our package.
To double-check, I downloaded our previous submission from CRAN and
checked it again. It's strange that this current CRAN version also has
this note now. However, when submitting it last December, there were
no such notes. Do you have any idea why the R CMD Check results are
inconsistent?
You could check on Winbuilder as that is a concrete setup used for
incoming checks. But in principle, the computation may take longer
because of changes in dependencies, external software and R. Which can
be due to a performance regression, a bugfix, etc. Only
debugging/profiling could reveal the true cause.
Yes, it may even be some OS update, or just coincidence that the system
was idling the last time your package got checked.
Note that CRAN systems are expected to be slower than, e.g., your
laptop, as the servers use multi core CPUs with rather low frequencies.
Best,
Uwe Ligges
Since the examples caused no note in the last submission and were
successfully submitted to CRAN, I'm not sure whether I should change
the examples in this re-submission to eliminate this sudden note. Any
suggestions will be appreciated!
If you were close to the limit last time, it may be a coincidence and
you might simply reduce the examples to be on the safe side.
Tomas
Thank you!
Ying
