[R] Estimating Survival function in coxph

Assuming that I have used the coxph function to fit a Cox model with several
covariates, is there a natural way to estimate a value of the survivorship
function at, say, five years,
S(5), along with a confidence interval? I have brought this question up
with one or two colleagues, who have suggested using a parametric model, but
I wonder whether it can be done using the semiparametric coxph() model.
