##### Adjust Colors in One or More Directions Conveniently.

Adjust or modify a vector of colors by “turning knobs” on one or more coordinates in $(r,g,b,\alpha)$ space, typically by up or down scaling them.

##### Usage
adjustcolor(col, alpha.f = 1, red.f = 1, green.f = 1, blue.f = 1, offset = c(0, 0, 0, 0), transform = diag(c(red.f, green.f, blue.f, alpha.f)))
##### Arguments
col
vector of colors, in any format that col2rgb() accepts
alpha.f
factor modifying the opacity alpha; typically in [0,1]
red.f, green.f, blue.f
factors modifying the “red-”, “green-” or “blue-”ness of the colors, respectively.
offset
transform
##### Value

col, effectively the result of rgb().
