Later dplyr and tidyr functions
Verification
Scope
across() edge cases, group helpers, superseded functions, pivot options and specifications, rectangling, and other dplyr 1.1 and tidyr 1.3 functions. Results compared with R's.

Data
Method
Reference results computed in R by tests/r/coverage.R and stored in tests/Fixtures/. The same operations run in phplyr in tests/CoverageTest.php, which compare every value. Values compared is the number of assertions in a case; a case fails if any assertion fails.

Tolerances
|x − r| ≤ 1e-9 + 1e-9 × max(|r|, 1)
Applies to: Floating-point values
exact equality
Applies to: Column names, row counts and order, strings, integers, booleans, dates, and missing values
x: package value; r: reference value. Absolute error: |x − r|. Relative error: |x − r| / max(|r|, 1). Max errors are over the values a row compares.
Results
26 comparisons: 26 pass, 0 fail, 0 skipped.
