[R] modify a nomogram

[Frank Harrell]

Update to the rms package which is the version now being actively 
supported.  New features will not be added to Design.  The nomogram 
function in rms separates the plotting into a plot method for easier 
understanding.  You can control all axes - some experimentation can 
tell you if you can do what you want as I haven't tried exactly what 
you are doing.
