[BioC] Displaying multiple survival curves on one graph

[Seth Falcon]

Hi Rifat,

I think this question might be more appropriate for R-help.  

I would recommend trying RSiteSearch() to look for possible solutions
to your question.

Conceptually, I suspect what you will need to do is:

 - plot one survfit result
 - use lines() or points() and the relevant data extracted from the
   other fits to add to the existing plot.

HTH,
