Currently, IncidencePrevalence package is a flexible tool for calculating incidence rate. However, another and even simpler method for describing incidence is Incidence Proportion (cumulative incidence):
IP=number of new cases during period / Number of healthy people at the beginning of period
Numerator counts only the cases of people that were present at the beginning of the period.
See more: https://en.wikipedia.org/wiki/Incidence_(epidemiology) and https://www.sciencedirect.com/topics/medicine-and-dentistry/cumulative-incidence
While Incidence Proportion is more naive than Incidence Rate, it is commonly used due to its simpler intuition and interpretation. Unfortunately, IncidencePrevalence package does not calculate Incidence Proportion.
Request: add feature to calculate Incidence Proportion in addition to incidence rate.
