Returns a color vector of rainbow colors. This is a special case of the combinedx() function.

Description

Returns a color vector of rainbow colors. This is a special case of the combinedx() function.

Usage

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	is the transparency.
...	methods passed on to sub-functions (not used, but allowing for unused arguments).

Examples

## Not run: 
x=runif(1000)
pp(1,2)
plot(x, pch=".", cex=30, col=rainbowx(x))
plot(x, pch=".", cex=30, col=rainbowx(x, flip=TRUE))

## End(Not run)
