calc_pd() and score_pd(). ep50 changed to etheta50 and corrected calculation of ep50.calc_pd() (and score_pd(), timing_pd(), and ans_pd).score_dd() that would unintentionally drop all rows if both conditions were FALSE.Rename example data from five.fivetrial to five.fivetrial_dd for delay discounting.
Add example data five.fivetrial_pd for probability discounting.
score_mcq27() properly supports arguments: impute_method, random, return_data, and verbose. See documentation and the README for explanations.
generate_data_mcq() can generate fake MCQ data, including seed and prop_na arguments for reproducibility and specifying proportion of NAs.
long_to_wide* and wide_to_long* are helper functions to reshape data from/to different formats.
NAs exist in the data, score_mcq27() returns NAs for the scoring instead of 1.Initial release with basic scoring of 27-item Monetary Choice Questionnaire and 5.5 trial delay discounting task from the Qualtrics template.
Added a NEWS.md file to track changes to the package.
