Hello all, My package *WeightIt* is failing <https://cran.r-project.org/web/checks/check_results_WeightIt.html> the CRAN test on ATLAS. The failure is due <https://www.stats.ox.ac.uk/pub/bdr/Rblas/ATLAS/WeightIt.out> to a failed *testthat* test comparing two covariance matrices using check_equal(). A few things are confusing to me, so I'm not sure how to solve it.
First, the covariance matrices should be identical; there is no random component in their computation and the the only difference in the calls used to generate them are whether an argument is omitted or whether it is explicitly set to its default (i.e., the purpose of the test is to ensure the default argument corresponds to the supplied argument). I am willing to accept that there is some non-deterministic process in ATLAS, e.g., where convergence is measured based on time rather than number of iterations, though I don't know if this is actually the case. Second, the package tests have passed on previous CRAN checks (this is weeks after this version was accepted to CRAN), on all other versions of R, and in the rhub test <https://github.com/ngreifer/WeightIt/actions/runs/11489721542/job/31979056981#step:6:124> with ATLAS. Does anyone have any advice on how to solve this? I know I can change the tolerance argument to check_equal() but this is a case where the output should be identical. I cannot reproduce the problem with rhub, so I can't see where the problem is. Could this be a false alarm due to caching? Thanks for any insights.
