What would I do if I have something like:
x <- rnorm(1:1000)
y <- rnorm(1:1000)
z <- x + y
and I want the rainbow to increase with z? (i.e., red for lowest z...all
the way up to the last color in the rainbow for the highest z)

Why would you want to? See
http://epub.wu-
On second thought, this is more likely to be what you're looking for...
library(rgl)
x <- rnorm(1000)
y <- rnorm(1000)
z <- x + y
plot3d(x, y, z, col = rainbow(1000, end = 5/6)[rank(z)], size = 3)

plot(1:20, col=rainbow(20))

Hi, how can I create a rainbow gradient in R? For example, let's say I have
a plot of y = x...and I want the plot to go from red -> orange -> yellow ->
green -> blue -> etc.
Right now, I know how to do something like go from red to blue, using the
plotrix library:
library(plotrix)
redToBlue <-
col
