Plot a cost-effectiveness acceptability frontier (CEAF) from the output of
`cea`

using `ggplot2::ggplot`

. The CEAF plots the probability
that the optimal treatment strategy (i.e., the strategy with the highest
expected net monetary benefit) is cost-effective.

See the `cea()`

documentation for an example. If there are multiple subgroups,
then a faceted plot is produced with one plot for each subgroup.
