stam.rgb.colors {stam} | R Documentation |
Generates a colur gradient starting from one color given by the user and ending in another going through black.
stam.rgb.colors(n = 12, m = 1, r0 = 1, g0 = 0, b0 = 0, r1 = 0, g1 = 1, b1 = 0)
n |
Number of shades generated in the color gradient |
m |
skewing factor. m=1 produces a linear gradient from start to black and from black to end. High m decreases the amount of black, low m's increase it. |
r0 |
red component of the starting color |
g0 |
green component of starting color |
b0 |
blue component of the starting color |
r1 |
red component of the ending color |
g1 |
green component of the ending color |
b1 |
blue component of the ending color |
A charactor vector of length 2*n. Each element represents the code of an RGB color.
