panel.key {latticeExtra} | R Documentation

## Draw a simple key inside a panel of a lattice plot.

### Description

Draw a `simpleKey` inside a panel of a lattice plot.

### Usage

    panel.key(text, ..., corner = c(0, 1), x = corner[1], y = corner[2])

### Arguments

`text, ...` | entries in the `simpleKey`.
`corner, x, y` | defines the position of the key within the panel viewport. These are given in normalised coordinates between 0 and 1. The two elements of `corner` specify the x and y positions respectively.

### See Also

### Examples

    xyplot(ozone ~ wind | equal.count(temperature, 2),
           data = environmental) +
       layer(panel.loess(x, y, span = 0.5), style = 1) +
       layer(panel.loess(x, y, span = 1.0), style = 2) +
       layer(panel.key(c("span = 0.5", "span = 1.0"), corner = c(1,.98),
                       lines = TRUE, points = FALSE), packets = 1)
