Aggregate types
Verification
Scope
Result type of 22 aggregates in a grouped summarise() where every group holds only NA.
References
- Reference
- dplyr 1.2.1 summarise(), on R 4.6.1
- Versions
- R 4.6.1, dplyr 1.2.1, jsonlite 2.0.0, PHP 8.5.10
Data
- all-NA table
- 4 rows in 2 groups; NA double, integer, logical, character, and date columns Source
Method
tests/r/expr-types.R records the column type dplyr gives each aggregate. tests/AggregateTypeTest.php runs the same summaries on a DataFrame. Fixtures regenerated with the listed R versions on 2026-11-01; output byte-identical to the committed files.
