53_predefined_litmus-fitting_functions: Predefined Litmus-Fitting Functions

Description

Functions that wrap the main litmus-fitting function, with predefined colors.

Usage

green.litmus.fit (x, …, reverse=FALSE, equalize=0.85)
heat.litmus.fit (x, …, reverse=FALSE, equalize=0.85)
blue.litmus.fit.hcv (x, …, reverse=FALSE, equalize=0.85)
green.litmus.fit.hcv (x, …, reverse=FALSE, equalize=0.85)
blue.litmus.fit.flow (x, …, reverse=FALSE, equalize=0.85)
green.litmus.fit.flow (x, …, reverse=FALSE, equalize=0.85)
gold.litmus.fit.lum (x, …, reverse=FALSE, equalize=0.85)
blue.litmus.fit.lum (x, …, reverse=FALSE, equalize=0.85)
green.litmus.fit.lum (x, …, reverse=FALSE, equalize=0.85)
purple.litmus.fit.lum (x, …, reverse=FALSE, equalize=0.85)
heat.litmus.fit.lum (x, …, reverse=FALSE, equalize=0.85)
rainbow.litmus.fit (x, …, c=42.5, l=75, start=65, end=315,
    equalize=0.85)
rainbow.litmus.fit.2 (x, …, c=50, l=70, start=0, end=360,
    equalize=0.85)
glass.rainbow.fit (x, alpha=0.3, …, c=42.5, l=62.5, start=42.5, end=260,
    equalize=0.85)
hot.and.cold.fit (x, …, t=0, hot.hue=35, cold.hue=255,
    equalize=0.85)

Arguments

x

A numeric vector.

reverse

Logical, reverse the order of the colors.

equalize

Numeric, between zero and one, refer to details, for litmus.fit.

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 knot.

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.

hot.hue, cold.hue

Numerics, the hot and cold hues.

…

Ignored.

Value

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

Details

Most of these functions wrap the litmus.fit function.

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

Examples

# NOT RUN {
x <- rnorm (30)

colf1 <- blue.litmus.fit (x)
colf2 <- hot.and.cold.fit (x)

p0 <- par (mfrow = c (2, 1) )
plot (colf1)
plot (colf2)
par (p0)

u <- seq (min (x), max (x),, 5)
colf1 (u)
colf2 (u)
# }
