A small creel interview data frame with intentional data quality issues
for demonstrating validate_creel_data() and standardize_species().
Includes an empty species string, a negative fish_kept value, and a
missing trip_hours value.
Format
A data frame with 6 rows and 5 columns:
- date
Interview date (Date class).
- day_type
Day type stratum:
"weekday"or"weekend".- species
Free-text species name; includes empty string and unrecognised value to demonstrate
standardize_species()behaviour.- fish_kept
Number of fish kept; one row is intentionally negative.
- trip_hours
Trip duration in hours; one row is intentionally
NA.
