Removal of elements from nomograms
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

I have aproblem about nomogram--thank you for your help
dear professor:
I have a problem about the nomogram.I have got the result through analysing the dataset "exp2.sav" through multinominal logistic regression by SPSS 17.0.
and I want to deveop the nomogram through R-Projject,just like this :
> n<-100
> set.seed(10)
> T.Grade<-factor(0:3,labels=c("G0", "G1", "G2","G3"))
