ggrect {ggplot} | R Documentation

## Grob function: rectangle

### Description

Add rectangles to a plot

### Usage

    ggrect(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

This grob provides the basic functionality required by `ggbar` and `ggtile`. You should probably not call it yourself

Aesthetic mappings that this grob function understands:

- `x`:x position (required)
- `y`:y position (required)
- `width`:width of the rectangle (required)
- `height`:height of the rectangle (required)
- `fill`:fill colour (see `sccolour)`

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:

- `justification`:justification of the bar relative to its (x, y) location, see `rectGrob for more details`
