RGB	R Documentation

Create RGB Colors

This function creates colors of class RGB; a subclass of the virtual “color” class.

RGB(R, G, B, names)

`R,G,B`	these arguments give the red, green and blue intensities of the colors (the values should lie between 0 and 1). The values can be provided in separate `R`, `G` and `B` vectors or in a three-column matrix passed as `R`.
`names`	A vector of names for the colors (by default the row names of `R` are used).

This function creates colors in the linearized sRGB color space (IEC standard 61966).

An object of class “RGB” which inherits from class “color.”
