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.

Examples

# create a vector of colors
cols <- delim_brewer(geophagus_delims, package = "randomcoloR")
