cumulate: Compute cumulative 'incidence'

In incidence: Compute, Handle, Plot and Model Incidence of Dated Events

Compute cumulative 'incidence'

Description

cumulate is an S3 generic to compute cumulative numbers, with methods for different types of objects:

Usage

cumulate(x)

## Default S3 method:
cumulate(x)

## S3 method for class 'incidence'
cumulate(x)

Arguments

x	An incidence object.

Details

• default method is a wrapper for cumsum

• incidence objects: computes cumulative incidence over time

• projections objects: same, for projections objects, implemented in the similarly named package; see ?cumulate.projections for more information, after loading the package

Examples

dat <- as.integer(c(0,1,2,2,3,5,7))
group <- factor(c(1, 2, 3, 3, 3, 3, 1))
i <- incidence(dat, groups = group)
i
plot(i)

i_cum <- cumulate(i)
i_cum
plot(i_cum)
