R: Hexbin Plot Matrices

hexplom {hexbin} | R Documentation

## Hexbin Plot Matrices

### Description

`hexplom` draws Conditional Hexbin Plot Matrices. It is similar to `splom`, expect that the default display is different. Specifically, the default display is created using `panel.hexplom`, which is an alias for `panel.hexbinplot`.

### Usage

    hexplom(x, data, ...)

    ## S3 method for class 'formula'
    hexplom(x, data = NULL, ...)

    ## S3 method for class 'data.frame'
    hexplom(x, data = NULL, ..., groups = NULL,
       subset = TRUE)

    ## S3 method for class 'matrix'
    hexplom(x, data = NULL, ..., groups = NULL, subset = TRUE)

    panel.hexplom(...)

### Arguments

`x` | The object on which method dispatch is carried out. For the `"formula"` method, a formula describing the structure of the plot, which should be of the form `~ x | g1 * g2 * ...`, where `x` is a data frame or matrix. Each of `g1, g2, ...` must be either factors or shingles. The conditioning variables `g1, g2, ...` may be omitted. For the `data.frame` and `matrix` methods, a data frame or matrix as appropriate.
`data` | For the `formula` method, an optional data frame in which variables in the formula (as well as `groups` and `subset`, if any) are to be evaluated. By default, the environment where the function was called from is used.
`groups, subset, ...` | see `splom`. The non-standard evaluation of `groups` and `subset` only applies in the `formula` method. Apart from arguments that apply to `splom` (many of which are only documented in `xyplot`), additional arguments meant for `panel.hexplom` (which is an alias for `panel.hexbinplot`) may also be supplied. Such arguments may include ones that control details of the hexbin calculations, documented in `gplot.hexbin`

### Value

An object of class `"trellis"`. The `update` method can be used to update components of the object and the `print` method (usually called by default) will plot it on an appropriate plotting device.

### Examples

    ## Simple hexplom
    data(NHANES)
    hexplom(~NHANES[,7:14], xbins=15)

    ## With colors and conditioning
    hexplom(~NHANES[,9:13] | Sex, data = NHANES,
            xbins = 15, colramp = magent)

    ## With custom panel function
    hexplom(NHANES[,9:13], xbins = 20,colramp = BTY,
            upper.panel = panel.hexboxplot)
