[R] Zelig package: Coxph model problems

[Stephen Knight]

Hi,

I'm having problems with the Zelig package - when using 
the below R displays the follwing message (I'm running R 
i386 2.15.3 for Windows and have updated all the Zelig 
packages):

z.out<-zelig(Surv(psurv2, pcens2) ~ ren_sup3 + age,
		data=data_urgent, model="coxph")

** The model "coxph" is not available with the currently 
loaded packages,
** and is not an official Zelig package.
** The model's name may be a typo.

Any suggestions?

Regards,
Steve Knight
