ch_circular_colors: Color Palettes for Circular

In CSHShydRology: Canadian Hydrological Analyses

Color Palettes for Circular

Description

Produces a vector of n contiguous colours. The original version from the package circular produced n colours with 1 and n being the same colour. This version internally produces n + 1 colours and removes the repeated end colour so there are n unique colours. Hue is calculated for points on the circle. Saturation and value default to 0.85. Default alpha is 1.0 - no transparency.

Usage

ch_circular_colors(
  n,
  m = 0,
  M = 2 * pi,
  offset = 0,
  s = 0.85,
  v = 0.85,
  alpha = 1
)

Arguments

n	the number of colours (<= 1) to be in the palette
m	the smallest angle in radians
M	the largest angle in radians
offset	the zero in radians
s	saturation further arguments passed to the function hsv
v	value [0.85]
alpha	alpha [1.0] no transparency

Value

a vector of length n
