epiparameter (version 0.4.1)

plot.epiparameter: Plot method for <epiparameter> class

Description

Plot an <epiparameter> object by displaying the either the probability mass function (PMF), (in the case of discrete distributions) or probability density function (PDF) (in the case of continuous distributions), or the cumulative distribution function (CDF).

Usage

# S3 method for epiparameter
plot(x, cumulative = FALSE, ...)

Value

These functions are invoked for their side effect of drawing on the active graphics device.

Arguments

x

An <epiparameter> object.

cumulative

A boolean logical, default is FALSE. cumulative = TRUE plots the cumulative distribution function (CDF).

...

further arguments passed to or from other methods.

Details

By default if the xlim argument is not specified the distribution is plotted between day 0 and the 99th quantile of the distribution. Alternatively, a numeric vector of length 2 with the first and last day to plot on the x-axis can be supplied to xlim (through ...).

Examples

# plot continuous epiparameter
ep <- epiparameter(
  disease = "ebola",
  epi_name = "incubation_period",
  prob_distribution = create_prob_distribution(
    prob_distribution = "gamma",
    prob_distribution_params = c(shape = 2, scale = 1)
  )
)
plot(ep)

# plot different day range (x-axis)
plot(ep, xlim = c(0, 10))

# plot CDF
plot(ep, cumulative = TRUE)

# plot discrete epiparameter
ep <- discretise(ep)
plot(ep)
