52_predefined_litmus_objects: Predefined Litmus Objects

Description

Functions that wrap the main litmus constructor, with predefined colors.

Usage

gold.litmus (a=0, b=1)
blue.litmus (a=0, b=1)
green.litmus (a=0, b=1)
heat.litmus (a=0, b=1)
blue.litmus.hcv (a=0, b=1)
green.litmus.hcv (a=0, b=1)
blue.litmus.flow (a=0, b=1)
green.litmus.flow (a=0, b=1)
rainbow.litmus (a=0, b=1, …, c=42.5, l=75, start=65, end=315)
rainbow.litmus.2 (a=0, b=1, …, c=50, l=70, start=0, end=360)
glass.litmus (a=0, b=1, alpha=0.3, …, c=42.5, l=62.5, start=42.5, end=260)
hot.and.cold (t=0, d=1, …, hot.hue=35, cold.hue=255)

Arguments

a, b

Numerics, the lower and upper limits.

c, l, start, end

Same as colorspace::rainbow_hcl.

alpha

A numeric vector giving the alpha component. If it has two or more values, then each alpha value is assigned to each color.

t

Numeric of length one or two, giving the transition points between "hot" and cold". Two points can be used for a softer effect, but they should be relatively close.

d

Numeric of length one or two, giving the distance about the transition point.

hot.hue, cold.hue

Numerics, the hot and cold hues.

…

Ignored.

Value

All functions return litmus objects. (Except for hot.and.cold, which returns a mlitmus object).

Details

Most of these functions wrap the litmus function.

The rainbow.litmus and rainbow.litmus.2 functions are based on colorspace::rainbow_hcl.
