This function constructs palettes of the specified size based on the colour
maps developed by Fabio Crameri. It follows the same API style as viridis()
from the viridisLite package so anyone familiar with this package can
easily adapt to that.
Usage
scico(
n,
alpha = NULL,
begin = 0,
end = 1,
direction = 1,
palette = "bilbao",
categorical = FALSE
)
Value
A character vector of length n with hexencoded rgb(a) colour values
Arguments
n
The number of colours to generate for the palette
alpha
The opacity of the generated colours. If specified rgba values
will be generated. The default (NULL) will generate rgb values which
corresponds to alpha = 1
begin, end
The interval within the palette to sample colours from.
Defaults to 0 and 1 respectively
direction
Either 1 or -1. If -1 the palette will be reversed
palette
The name of the palette to sample from. See
scico_palette_names() for a list of possible names
categorical
Boolean. Should the categorical palettes be returned
# Use the default palettescico(15)
# Flip the directionscico(15, direction = -1)
# Take a subset of a palettescico(15, begin = 0.3, end = 0.6, palette = 'berlin')
