[R] Removal of elements from nomograms

[Rob James]

The rms package includes the nomogram function, which generates a list 
object that can be passed to plot for graphical production of nomograms.

I would like to remove  the "linear predictor" line in the graph, which 
means (I suspect) removing it from the nomogram output object.  I've 
looked at the nomogram output object, but it is not clear to me if or 
how it might be edited to remove the linear predictor content. Similarly 
, I do not see how to coax  nomogram()  into not producing this output 
in the first place.

As ever, thanks in advance are likely due to Frank Harrell, without whom 
many things would be much more difficult.
