These are included here because pals depends on a number of compiled packages, and this can lead to increases in run time for Travis, and generally should be avoided when possible.

DiscretePalette(n, palette = NULL)

## Arguments

n Number of colours to be generated. Options are "alphabet", "alphabet2", "glasbey", "polychrome", and "stepped". Can be omitted and the function will use the one based on the requested n.

## Value

A vector of colors

## Details

These palettes are a much better default for data with many classes than the default ggplot2 palette.
