52_predefined_litmus_objects: Predefined Litmus Objects

In barsurf: Contour Plots, 3D Plots, Vector Fields and Heatmaps

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.

Details

Most of these functions wrap the litmus function.

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

Value

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