R: Texture Map

texturemap {spatstat} | R Documentation

## Texture Map

### Description

Create a map that associates data values with graphical textures.

### Usage

    texturemap(inputs, textures, ...)

### Arguments

`inputs` | A vector containing all the data values that will be mapped to textures.
`textures` | Optional. A vector of integer codes specifying the textures to which the `inputs` will be mapped.
`...` | Other graphics parameters such as `col`, `lwd`, `lty`.

### Details

A texture map is an association between data values and graphical textures. The command `texturemap` creates an object of class `"texturemap"` that represents a texture map.

Once a texture map has been created, it can be applied to any suitable data to generate a texture plot of those data using `textureplot`. This makes it easy to ensure that the same texture map is used in two different plots. The texture map can also be plotted in its own right.

The argument `inputs` should be a vector containing all the possible data values (such as the levels of a factor) that are to be mapped.

The `textures` should be integer values between 1 and 8, representing the eight possible textures described in the help for `add.texture`. The default is `textures = 1:n` where `n` is the length of `inputs`.

### Value

An object of class `"texturemap"` representing the texture map.
