Have you looked at library(survival)?  Unless I misunderstand what you 
want, it should be there.  Further documentation is provided in Venables 
and Ripley (2002) Modern Applied Statistics with W, Therneau and 
Grambsch (2000) Modeling Survival Data, Harrell (2001) Regression 
Modeling Strategies (all Springer), and in materials downloadable from 
www.r-project.org;  see especially search -> "R site search".  Have you 
tried these sources? 

      hope this helps.  spencer graves
