Returns a color vector of the requested length, ranging from pure red to pure green via slighlty tinted black.
g2r.colors(n = 12, min.tinge = 0.33)
the number of requested colors
the proportion of red/green added to black to make it recognizably green or red
n is even, the colors range from pure green to green-tinted black to red-tinted black to pure red. If
n is odd, the colors range from pure red to pure green, with full black for the median class.
A vector of (RGB-) colors of the specified length
1 2 3 4 5 6 7 8 9 10 11 12 13 14
## Even number: residual tint shows left/right of center co_even = g2r.colors(10) co_even doLegend(1:11, co_even, 1) ## Odd number: central class all black co_odd = g2r.colors(9) co_odd doLegend(1:10, co_odd, 1) ## Lighter tint in the middle co_light = g2r.colors(10, min.tinge=0.50) co_light doLegend(1:11, co_light, 1)
