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)
```
