class_pred objects are now comparable and will be ordered by their levels. Equivocal values are generally considered to be the smallest value when ordering. NA values can be considered smaller if vec_order(na_value = "smallest") is used.Suggest the modeldata package, which is where the lending_club dataset has been moved after being removed from recipes.
Use testthat::verify_output() on a test expecting a specific vctrs error to avoid failure on CRAN if that error changes in the future.
probably has been brought up to date with vctrs 0.2.0. This vctrs update had many function name changes, and required internal refactoring, but there should be minimal external changes.
The one user facing change comes with casting from one class_pred object to another class_pred, or to a factor. Where previously a warning would be thrown if x had levels that did not exist in to, an error is now generated. This is consistent with the vctrs behavior when converting from one factor to another.
x <- class_pred(factor("a"))
to <- class_pred(factor("to"))
vec_cast(x, to)
#> Error: Lossy cast from <class_pred> to <class_pred>.
#> Locations: 1A failing test relying on the R 3.6 change to sample() has been corrected.
An rlang warning in threshold_perf() has been fixed.
A small R 3.1 issue with vctrs has been fixed.
