R Users,

        I am using the AKIMA contrib package to generate a 2D colored 
contour plot.

        The code generates a contour value color legend adjacent the plot 
based on the range of 
Z values in the plot.

        Is there some way to make the association between Z values and 
color scale absolute
rather than relative i.e., I want dark green to always mean Z = 4.00 even 
if I don't have any data 
with that Z value.  Or, I want red to always mean Z = 9.00 whether or not 
I have data points with 
those values.  I also want to always display the same exact color scale.

        Otherwise, it is difficult to compare contour plots because the 
colorization is not standard.

        Does anyone know of R code to do this?

        Thank you.

        Regards,
        Jim Metz
