Description
as.rgb() converts a value in the HSL (hue-saturation-lightness)
color model or a hexadecimal code for a value in the RGB (red-green-blue)
color model to a value in the RGB color model.
Usage
1
as.rgb(x)
Arguments
x
A character string or a numeric vector with 3 elements.
A character string is assumed to be the hexadecimal code for a value in
the RGB color model;
a numeric vector is assumed to be a value in the HSL color model.
Details
If x is a character string, then it is assumed that x is
a hexadecimal code ('#RRGGBB') whose substrings denote the the values
of the red ('RR'), green ('GG'), and blue ('BB') beams.
If x is a numeric vector (but not an integer vector), then it is
assumed that x denotes a value in the HSL color model—i.e.,
that the first element of x is an whole number between 0 and 359,
denoting the angle of the hue on the color wheel;
that the second element is a floating point number (to 2 decimal places)
between 0 and 1, denoting the saturation proportion;
that the third element is a floating point number (to 2 decimal places)
between 0 and 1, denoting the lightness proportion.
Value
An integer vector with three elements (valued between 0 and 255) that
denote the values of the red, green, and blue beams, respectively.
