View source: R/iwanthue.R

Generate a palette of distinct colours through k-means clustering of CIE Lab colour space.

iwanthue(
  n,
  hmin = 0,
  hmax = 360,
  cmin = 0,
  cmax = 180,
  lmin = 0,
  lmax = 100,
  plot = FALSE,
  random = FALSE
)

`n`	Numeric. The number of colours to generate.
`hmin`	Numeric, in the range `[0, 360]`. The lower limit of the hue range to be clustered.
`hmax`	Numeric, in the range `[0, 360]`. The upper limit of the hue range to be clustered.
`cmin`	Numeric, in the range `[0, 180]`. The lower limit of the chroma range to be clustered.
`cmax`	Numeric, in the range `[0, 180]`. The upper limit of the chroma range to be clustered.
`lmin`	Numeric, in the range `[0, 100]`. The lower limit of the luminance range to be clustered.
`lmax`	Numeric, in the range `[0, 100]`. The upper limit of the luminance range to be clustered.
`plot`	Logical. Should the colour swatches be plotted (using `swatch()`)?
`random`	Logical. If `TRUE`, clustering will be determined by the existing RNG state. If `FALSE`, the seed will be set to `1` for clustering, and on exit, the function will restore the pre-existing RNG state.

Note that iwanthue currently doesn't support hmin greater than hmax (which should be allowed, since hue is circular).

A vector of n colours (as hexadecimal strings), representing centers of clusters determined through k-means clustering of the CIE Lab colour space delimited by hmin, hmax, cmin, cmax, lmin and lmax.
