b: vector of ‘blue’ values, or NULL when r is a matrix.

Example 1:

# R program to illustrate
# rgb2hsv function

# Calling the col2rgb() function to
# get color in rgb
rgb = col2rgb("# 08a0ff")

# Calling the rgb2hsv() function to
# convert the RGB values in the
# colormap to HSV
rgb2hsv(rgb)

Output:

       [, 1]
h 0.5641026
s 0.9686275
v 1.0000000

Example 2:

# R program to illustrate
# rgb2hsv function

# Calling the rgb2hsv() function
rgb2hsv(60, 120, 180)

Output:

       [, 1]
h 0.5833333
s 0.6666667
