plot.dist_spec: Plot PMF and CDF for a dist_spec object

Description

This function takes a dist_spec object and plots its probability mass function (PMF) and cumulative distribution function (CDF) using ggplot2. Note that currently uncertainty in distributions is not plot.

Usage

# S3 method for dist_spec
plot(x, ...)

Arguments

x

A dist_spec object

...

Additional arguments to pass to ggplot

Examples

#' # A fixed lognormal distribution with mean 5 and sd 1.
lognormal <- dist_spec(
  mean = 1.6, sd = 0.5, max = 20, distribution = "lognormal"
)
plot(lognormal)

# An uncertain gamma distribution with mean 3 and sd 2
gamma <- dist_spec(
  mean = 3, sd = 2, mean_sd = 0.5, sd_sd = 0.5, max = 20,
  distribution = "gamma"
)
plot(gamma)

# Multiple distributions
plot(lognormal + gamma + lognormal)

# A combination of the two fixed distributions
plot(lognormal + lognormal)
