make.gradient: Make a colour gradient.

In monorunner/smcolors: SM colour tools.

Description

Make a colour gradient.

Usage

make.gradient(..., len = 5, fixed = NULL, order = FALSE, plot = TRUE,
  texts = TRUE)

Arguments

...	Color names.
len	Length of the gradient. If more than two colors, the length of the step (A 4-colour gradient with len = 5 gives 15 colours).
fixed	A concatenated string indicating the fixed component(s) of the gradient. One or two components (letters) of either "rgb" or "hsv" can be specified. See details.
order	If TRUE, colours are ordered to make a continuous gradient from dark to light.
plot	Whether to plot the gradient bar. Default TRUE.
texts	Whether to add text labels to the bar. Default TRUE

Details

Examples of valid fixed are "hv", "h", "rg" etc. Two-colour gradient cannot be used in combination with fixed. If only one colour is specified, the colour's position in the gradient is decided by its brightness (if fixed is NULL) or by its value of the first fixed component (if fixed is specified).

Value

A vector of colour names.

Examples

make.gradient()
make.gradient("turquoise", fixed = "hv")
make.gradient(cyans[1], blues[9], len = 8)
make.gradient(blues[1], reds[1], yellows[1], cyans[1])
