This is how benchmark results would change (along with a 95% confidence interval in relative change) if 423830d is merged into main:

•   :ballot_box_with_check:cache_applying: 27.3ms -> 27.2ms [-0.97%, +0.35%]
•   :ballot_box_with_check:cache_recording: 746ms -> 744ms [-0.74%, +0.13%]
•   :ballot_box_with_check:without_cache: 1.86s -> 1.87s [-0.17%, +0.57%]

Further explanation regarding interpretation and methodology can be found in the documentation.

Another option would be as.data.frame(matrix(ncol = 3, byrow = TRUE, c(...)))

Thanks for the suggestion. But I think I will just retain it like this for now.
