R color palettes for many data classes

Question

Are there any good packages for colour palettes in R that can handle many data classes? I have 16 sequential data classes. I tried RColorBrewer but it has a max of 9 data cl

Answer 1

The Polychrome package allows to create palettes with many distinct colors. Some examples:

# install.packages("Polychrome")
library(Polychrome)

# build-in color palette
Glasbey = glasbey.colors(32)
swatch(Glasbey)

# create your own color palette (36 colors) based on `seedcolors`
P36 = createPalette(36,  c("#ff0000", "#00ff00", "#0000ff"))
swatch(P36)

# create your own color palette (50 colors) based on `seedcolors`
P50 = createPalette(50,  c("#ff0000", "#00ff00", "#0000ff"))
swatch(P50)
