colors: Color Names

Description

Returns the built-in color names which R knows about.

Usage

colors (distinct = FALSE)
colours(distinct = FALSE)

Arguments

distinct

logical indicating if the colors returned should all be distinct; e.g., "snow" and "snow1" are effectively the same point in the $(0:255{)}^3$ RGB space.

Value

A character vector containing all the built-in color names.

Details

These color names can be used with a col= specification in graphics functions.

An even wider variety of colors can be created with primitives rgb, hsv and hcl, or the derived rainbow, heat.colors, etc.

See Also

palette for setting the ‘palette’ of colors for par(col=<num>); rgb, hsv, hcl, gray; rainbow for a nice example; and heat.colors, topo.colors for images.

col2rgb for translating to RGB numbers and extended examples.

Examples

# NOT RUN {
cl <- colors()
length(cl); cl[1:20]

length(cl. <- colors(TRUE))
## only 502 of the 657 named ones
