help with survival package

I am trying use survfit function in survival package, but getting an error that
Error in survfit:  could not find function "survfit.km"

This package was working fine previously. I am using  R version 2.9.2 on Windows.

Can anyone tell me if this is a bug in the function code or something is missing in the newer version of R.

I appreciate any help regarding this.

Thanks

If you are using the current version of package survival with the  
prior version of R it should not be a surprise if there are  
incompatibilities.

Can anyone tell me if this is a bug in the function code or  
something is missing in the newer version of R.

No code, .... no comment.

I appreciate any help regarding this.

Thanks
