rainbowx(x, s = 1, v = 1, start = 0, end = 1, clamp = NULL,
  flip = FALSE, alpha = 1, ...)

Arguments

x

is a numeric object to which rainbow colors combined with lightening and darkening should be matched.

s

is the range of the saturation values applied to the colors, where lower values suppress saturation. The default induces a clean rainbow.

v

is the range of the value applied to the colors, where lower values causes darker colors. The default induces a clean rainbow.

start

and 'end' are the start and end colors, given as values in [0,1].

flip

is true if the color scale should be reversed.

alpha
