[R] missing values and survival analysis

[john.ferguson@yale.edu]

Hi everyone,

I'm analysing a survival analysis data set at the moment with missing 
values in the covariate and survival vectors (I have about 60 
variables).  I know there are some functions on the CRAN network to 
deal with missing values in general multivariate data.  Does anybody 
know of any package that deals with missing data specifically in the 
context of survival analysis.  Any help would be greatly appreciated.

Thanks,

john.
