cumulate.projections {projections}

Compute cumulative projections

Description

cumulate is an S3 generic to compute cumulative numbers defined in the package incidence. The method for projections objects turns predicted incidences into cumulative incidences over time.

Usage

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

Arguments

x

A projections object.

Examples

if (require(distcrete) &&
    require(incidence)) {

  ## simulate basic epicurve
  dat <- c(0, 2, 2, 3, 3, 5, 5, 5, 6, 6, 6, 6)
  i <- incidence(dat)


  ## example with a function for SI
  si <- distcrete("gamma", interval = 1L,
                  shape = 1.5,
                  scale = 2, w = 0)
  set.seed(1)
  pred_1 <- project(i, runif(100, 0.8, 1.9), si, n_days = 30)
  plot_1 <- plot(pred_1)

  ## cumulative predictions
  pred_1_cum <- cumulate(pred_1)
  pred_1_cum
  plot(pred_1_cum)
}
