ggpolygon {ggplot} | R Documentation

## Grob function: polygon

### Description

Add polygons to a plot

### Usage

    ggpolygon(plot = .PLOT, aesthetics=list(), ..., data=plot$data)

### 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)
- id: identifier variable used to break up into multiple polygons
- size: size of the outline, in mm (see `scsize)`
- colour: outline colour (see `sccolour)`
- fill: internal 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:

- none
