calc_ncases

Calculate the number of sports-related cases (e.g. injuries) that occurred in
a cohort during a period.

Sports Injury Data analysis aims to identify and describe the
magnitude of the injury problem, and to gain more insights (e.g.
determine potential risk factors) by statistical modelling approaches.
The 'injurytools' package provides standardized routines and utilities
that simplify such analyses. It offers functions for data preparation,
informative visualizations and descriptive and model-based analyses.
