alpha |
The alpha transparency, a number in [0,1], |
begin |
The (corrected) hue in [0,1] at which the color map begins. |
end |
The (corrected) hue in [0,1] at which the color map ends. |
direction |
Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed. |

color code for NA values |
scale_from |
input range (vector of length two). If not given, is calculated from the range of x |
