mapcol: Scale Qualitative Values to Color

In TnT: Interactive Visualization for Genomic Features

Description

A simple util function that scales a factor to color based on the palette function.

Usage

mapcol(value, palette.fun = grDevices::rainbow, ...)

Arguments

value	A factor or character vector that may have n unique values.
palette.fun	The palette function to generate colors. For example, terrain.colors.
...	Extra arguments passed to the palette function.

Value

A character vector as colors, with the same length of value. Same values in value will have the same color.

Examples

mapcol(iris$Species)
