The trekcolors package provides a collection of color palettes based on Star Trek. It also offers functions for custom palettes and scale_* functions for use with ggplot2.

Scale functions for use with ggplot2

geom_point(size = 5, alpha = 0.75)
p + scale_color_trek() # starfleet is default palette
p <- ggplot(diamonds, aes(carat, price, color = clarity)) +
geom_point()
p + scale_color_lcars("2357") # equivalent to scale_color_trek("lcars_2357")
p <- ggplot(diamonds, aes(carat, stat(count), fill = cut)) +
geom_density(position = "fill")

Palettes with named colors
The four LCARS palettes that have a year in their series name are special in that these official standard LCARS colors have formal names.
# lcars_pals() # print list of all LCARS palettes
lcars_colors() # full set of unique names across the four palettes
#> pale-canary tanoi golden-tanoi neon-carrot
#> "#FFFF99" "#FFCC99" "#FFCC66" "#FF9933"
#> eggplant lilac anakiwa mariner

In addition to these and all the other predefined palettes, custom palettes can be constructed using official LCARS color names. This is like colorRampPalette() but with the ability to recognize official LCARS color names. This functionality was leveraged by scale_color_lcars1() and scale_color_lcars2() seen above when making sequential or divergent palettes based on specific LCARS colors for use with ggplot.
