Chameleon

Overview

chameleon contains a set of functions for automatically assigning colors to multi-dimensional data. The colors are distinct (as much as possible) and also reflect the internal structure of the data (as much as possible).

See the published R package, the rdocumentation, or the latest github version documentation for details. Specifically, the vignette explains why and how to use this package.

Installation

To install it, use:

install.packages('chameleon')

Usage

In general, if you have a matrix whose rows represent some elements/observations and whose columns represent some variables/measurements, then use chameleon::data_colors to obtain a color for each row. You can pass this function the optional groups parameter which assigns a group to each row, to obtain a color for each group instead of a color for each row.

See the published R package, the rdocumentation, or the latest github version documentation's reference section for the list and description of the available functions.
