smoothPalette: Create a gradient corresponding to a numeric vector

In january3/myfuncs: loads a few functions I often need

Description

Create a gradient corresponding to a numeric vector

Usage

smoothPalette(x, max = NULL, min = NULL, palfunc = NULL, n = 10,
  symmetrical = FALSE)

Arguments

x	a numeric vector
max	value which corresponds to the right-hand side of the color gradient
min	value which corresponds to the left-hand side of the color
palfunc	palette function as returned by colorRampPalette. By default, it is a function generating a gradient from blue through white to red.
n	how many steps in the gradient
symmetrical	whether the palette should be symmetrical around 0 (with default palette, that means that "0" corresponds to the color "white"

Details

This function "converts" numbers to colors. It generates a gradient based on a particular palette function in which each color corresponds to a value or value range in a numeric vector. The lowest value (or the value equal to min, if specified) corresponds to one extreme of the gradient, and the highest (or the value equal to max, if specified) to the other extreme of the gradient.
