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, ...)
Examples
#' # A fixed lognormal distribution with mean 5 and sd 1.
dist1 <- LogNormal(mean = 1.6, sd = 0.5, max = 20)
plot(dist1)
# An uncertain gamma distribution with mean 3 and sd 2
dist2 <- Gamma(
mean = Normal(3, 0.5), sd = Normal(2, 0.5), max = 20
)
#> Warning: Uncertain gamma distribution specified in terms of parameters that are not the "natural" parameters of the distribution (shape, rate). Converting using a crude and very approximate method that is likely to produce biased results. If possible, it is preferable to specify the distribution directly in terms of the natural parameters.
plot(dist2)
# Multiple distributions
plot(dist1 + dist2 + dist1)
# A combination of the two fixed distributions
plot(dist1 + dist1)
