Printing
Verification
Scope
Printed output of echo, format(), and glimpse() for 38 tables: numeric magnitudes and rounding, dates, factors, list-columns, grouped, rowwise, wide, and empty tables.
References
- Reference
- tibble 3.3.1 and pillar 1.11.1 print() and glimpse(), on R 4.6.1
- Versions
- R 4.6.1, tibble 3.3.1, pillar 1.11.1, dplyr 1.2.1, jsonlite 2.0.0, PHP 8.5.10
Data
- print cases
- Identical tables in tests/PrintTest.php and tests/r/print.R Source
Method
tests/r/print.R writes tibble's output for each table to tests/fixtures/print. tests/PrintTest.php builds the same tables in phibble and compares the text. Fixtures regenerated with the listed R versions on 2026-11-01; output byte-identical to the committed files.
