Error in data.table::set(): not a resizable vector

[MLopez-Ibanez]

I am the maintainer of irace. CRAN has notified me of an error that started with data.table 1.18.0. See https://www.stats.ox.ac.uk/pub/bdr/M1mac/irace.out You can see one of the errors below.

This seems M1mac-specific. The same tests work in other targets.

I have no clue how to fix this problem. The error may be on my usage of data.table. In any case, any hints on how to fix or work-around the error would be welcome.

Thank you!

we had tracked the {irace} issue in #7501, thought it was solved. will check again. cc @ben-schwen who might remember more details.

We'll need to investigate this ourselves, but judging by the reports, I suspect that Prof. Ripley's system may be running an earlier submission of version 1.18.0 that we had to redo due to the the many reverse dependency failures that we had initially missed. In particular, we should have fixed this in #7501.

Thank you! I can wait. He give me until 31 of January.

If you want me to change the code in the package, please let me know. I can also submit a new version to force a rebuild in CRAN. Unfortunately, I don't have access to this M1mac target for testing.
