Per-group colour palette for an aniframe

Source: R/palette_animovement.R
palette_animovement.Rd

Builds a named character vector mapping trajectory group keys to colours. The colour scheme adapts to how many what and (non-time) when levels the aniframe has:

Usage

palette_animovement(data, palette = "Dark 3", single_hue = "#3A6FB0")

Arguments

data

An aniframe.

palette

Name of a qualitative palette accepted by grDevices::hcl.colors(). Default "Dark 3".

single_hue

Colour used when neither what nor when has more than one level.

Value

A named character vector of hex colours.

Details

  • single (one of each, or none): a single hue.

  • what (multiple what, one when): one qualitative hue per what level.

  • when (one what, multiple when): one qualitative hue per when level.

  • matrix (multiple of both): one hue per what level, then a lighter-to-darker shade of that hue per when level.

Names of the returned vector match the group keys returned by the internal grouping logic — the redundant axis is dropped when only one side varies.
