Compute cumulative projections

Source: R/cumulate.R

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.

# S3 method for projections
cumulate(x)

Arguments

x

A projections object.

See also

The project function to generate the projections objects.

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)
}
