delim_brewer() returns a set of colors created by interpolating or using color palettes from RColorBrewer, viridisLite or randomcoloR.

Usage

delim_brewer(delim, package = NULL, palette = NULL, seed = NULL)

Arguments

delim: Output from delim_join.
package: Package which contains color palettes. Available options are "RColorBrewer", "viridisLite" or "randomcoloR".
palette: A palette name. brewer.pal for RColorBrewer or viridis for viridisLite options.
seed: Integer. Number to initialize random number generator.

Value

A character vector of hexadecimal color codes.

Details

delim_brewer() interpolates over a color palette and returns a vector of random colors whose length is equal to the sum of unique species delimitation partitions in delim. For reproducibility, make sure to provide a seed. If not provided, Sys.time will be used as seed instead. One should also try different seeds to get best color combinations for plotting.
