incidence2 is an R package that implements functions and classes to compute, handle and visualise incidence from linelist data. It refocusses the scope of the original incidence package. Unlike the original package, incidence2 concentrates only on the initial calculation, manipulation and plotting of the resultant incidence objects.

You can install the released version of incidence2 from CRAN with:

install.packages("incidence2")

An overview of incidence2 is provided in the vignettes distributed with the package:

• vignette("incidence2", package = "incidence2")
• vignette("working-with-incidence2-objects", package = "incidence2")
