colors
Color Names
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.
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.
Value
-
A character vector containing all the built-in color names.
See Also

rainbow for a nice example;
and heat.colors, topo.colors for images.

examples.
Examples

cl <- colors()
length(cl); cl[1:20]
