Do you mean the sort of thing that can be found at http://www.nomogram.org ? (there is one there for bladder cancer) If so, that is simply a "form-filling" type of front-end to an algorithm behind the scenes, which calculates the risk. The real work lies in establishing the algorithm. Certainly, R can be of great help in this, but it is not possible to indicate which parts of R may be needed to acheieve it: that will depend on the data you have available. The front end (filled in by the user) can be constructed using (amongst other possibilities) the tcltk package. First, you need to get a good working knowledge of R. Good places to start are: http://www.stats.bris.ac.uk/R/manuals.html --> An Introduction to R http://www.stats.bris.ac.uk/R/other-docs.html --> R for Beginners --> Using R for Data Analysis and Graphics - Introduction, Examples and Commentary --> Simple R --> Practical Regression and Anova using R Even before that, you will need to decide what statistical methods (regardless of software) you will need in order to establish the models which will form the basis of your nomogram.
