palette_set.Rd
This function generates an HCL palette for visualizing a small set of distributions (i.e., eight or fewer) that are not ordered in a linear or cyclical sequence (e.g., a set of utilization distributions describing space use by five separate individuals in the same population or a set of four species distributions that depend on similar food resources).
palette_set(x, custom_hues)
x | RasterStack or integer describing the number of layers for which colors need to be generated. |
---|---|
custom_hues | vector of integers between -360 and 360 representing
hues in the color wheel. For further details, consult the documentation
for colorspace::rainbow_hcl. The length of the vector must equal the
number of layers described by |
A data frame with three columns:
layer_id
: integer identifying the layer containing the maximum
intensity value; mapped to hue.
specificity
: the degree to which intensity values are unevenly
distributed across layers; mapped to chroma.
color
: the hexadecimal color associated with the given layer and
specificity values.
palette_timecycle for cyclical sequences of distributions and palette_timeline for linear sequences of distributions.

palette_timeline()
