prettyGraphsHSVColorSelection

Algorithmically select HSV colors.

This function uses an HSV color selection algorithm to create HSV color palletes.

prettyGraphsHSVColorSelection(n.colors = 1, offset = NULL, h = 13, s = 0.75, v = 0.75)

`n.colors`	number of colors needed
`offset`	numeric (decimal/percentage). This number decides the distance between indices for color selection. If NULL, the golden ratio is selected.
`h`	numeric. The initial hue (see `hsv`).
`s`	numeric. The initial saturation (see `hsv`).
`v`	numeric. The initial value (see `hsv`).

a matrix

a matrix of colors are returned.
