panel.smooth {graphics} | R Documentation

## Simple Panel Plot

### Description

An example of a simple useful `panel` function to be used as argument in e.g., `coplot` or `pairs`.

### Usage

    panel.smooth(x, y, col = par("col"), bg = NA, pch = par("pch"),
                 cex = 1, col.smooth = "red", span = 2/3, iter = 3,
                 ...)

### Arguments

`x, y` | numeric vectors of the same length
`col, bg, pch, cex` | numeric or character codes for the color(s), point type and size of `points`; see also `par`.
`col.smooth` | color to be used by `lines` for drawing the smooths.
`span` | smoothing parameter `f` for `lowess`, see there.
`iter` | number of robustness iterations for `lowess`.
`...` | further arguments to `lines`.

### See Also

`coplot` and `pairs` where `panel.smooth` is typically used; `lowess` which does the smoothing.

### Examples

    pairs(swiss, panel = panel.smooth, pch = ".")  # emphasize the smooths
    pairs(swiss, panel = panel.smooth, lwd = 2, cex = 1.5, col = "blue")  # hmm...
