ch_circular_colors: 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
)
Value
a vector of length n
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
