# Plot the groups of a borrowing model and its benchmark models.

Source:`R/hb_plot_group.R`

`hb_plot_group.Rd`

Plot the groups against one another for a borrowing model (hierarchical or mixture) and the independent and pooled benchmark models.

## Usage

`hb_plot_group(borrow, pool, independent, outcome = c("response", "diff"))`

## Arguments

- borrow
A data frame returned by

`hb_summary()`

for the mixture or hierarchical model.- pool
A data frame returned by

`hb_summary()`

for the pooled model.- independent
A data frame returned by

`hb_summary()`

for the independent model.- outcome
Character of length 1, either

`"response"`

or`"diff"`

, the quantity to plot on the vertical axis.
