This function produces a color image (color bar) which can be used for
the legend to another color image obtained from the functions
image, maImage, or
maImage.func.
If "numeric", a vector containing the "z" values in the
color image, i.e., the values which are represented in the color
image. Otherwise, a "character" vector representing colors.
horizontal
If TRUE, the values of x are
represented as vertical color strips in the image, else, the values
are represented as horizontal color strips.
col
Vector of colors such as that generated by
rainbow, heat.colors,
topo.colors, terrain.colors, or similar
functions. In addition to these color palette functions, a new
function maPalette was defined to generate color
palettes from user supplied low, middle, and high color values.
scale
A "numeric" vector specifying the "z" values in the color
image. This is used when the argument x is a
"character" vector representing color information.
k
Object of class "numeric", for the number of labels displayed on
the bar.
