Changes in version 2.0.1 (2026-01-26) - calc_incidence() and calc_burden(), slightly modified. If the confidence interval lower bound is negative, then it is replaced by zero. - CITATION file added Changes in version 2.0.0 (2025-11-28) - The "nomenclature" now is changed: - player --> athlete; - injuries -> cases or/and sports-related health problem. - gg_injriskmatrix() -> gg_riskmatrix() - gg_injphoto() -> gg_photo() - gg_injbarplot() -> gg_rank() some new functionalities also added to these functions. - injsummary() function has been split into smaller functions and its name now is: injsummary() -> calc_summary(). New (auxiliary) functions created: - calc_ncases() - calc_ndayslost() - calc_exposure() - calc_mean_dayslost() - calc_median_dayslost() - calc_iqr_dayslost() - calc_incidence() - calc_burden(). - injprev() has been modified and named calc_prevalence(). Also, gg_injprev_polar() has been modified and named gg_prevalence(). - prepare_all() has been modified: some attributes have been removed, and, in general, has been made more efficient/faster. - Created some utility and help functions. Changes in version 1.0.3 (2023-11-14) - gg_injriskmatrix now has cont_max_x and cont_max_y arguments to (optionally) control the ranges of contour lines and allows to pass on more arguments to geom_contour(), e.g. bins = , binwidth = , etc. Changes in version 1.0.2 (2023-09-27) - Fixes in injsummary(): exposure for injury type corrected and proper conf_level. - Quit pipe operator %>% dependency. - Added vignette for modelling sports injury data (counts). - Added vignette for modelling sports injury data (events) Changes in version 1.0.1 (2023-02-01) - Maintenance update: fixes CRAN issues due to the new release of dplyr - New feature of joins integrated Changes in version 1.0.0 (2023-01-26) - Initial release version to CRAN
