ggboxplot {ggplot} | R Documentation

## Grob function: boxplot

### Description

Add box and whiskers

### Usage

    ggboxplot(plot = .PLOT, aesthetics=list(), ..., data=NULL)

### Arguments

`plot` | the plot object to modify
`aesthetics` | named list of aesthetic mappings, see details for more information
`...` | other options, see details for more information
`data` | data source, if not specified the plot default will be used

### Details

Aesthetic mappings that this grob function understands:

- `x`:x position (required)
- `y`:y position (required)
- `weight`: observation weights

These can be specified in the plot defaults (see `ggplot`) or in the `aesthetics` argument. If you want to modify the position of the points or any axis options, you will need to add a position scale to the plot. These functions start with `ps`, eg. `pscontinuous` or `pscategorical`

Other options:

- `breaks`:how to break up the x axis (only used if not already a factor)
- `orientation`: whether boxplots should be horizontal or vertical. If missing will automatically decide based on which variable is a factor.
- other arguments passed `boxplot`

    p2 <- ggplot(mtcars, aesthetics=list(x=mpg, y=factor(cyl)))
    ggpoint(p)
    ggboxplot(p)
    ggboxplot(p2)
    ggboxplot(p, fill="pink", colour="green")
    ggpoint(ggboxplot(p))
    ggboxplot(p)
