[R] How does the survfit.coxph calculate the survival value?

Dear Professor Terry Therneau,
Sorry for another naive question about R.

Some one suggested me to use mathematica to analyze Cox proportional hazard
model. For example estimate the coefficients, and calculate the survival and
hazard function.
But I think that may be not possible, especially that all the six covariates
in my model are time-dependent.

Could you please give me any opinion on this?
