This applies to formulas as well. You need to do some meta-programming for that to work. Here's one way to re-write your function to work WebWith Cox models, the linear combinations of factor levels for other contrasts and statistical tests will be taken on the coefficients themselves, not on the hazard ratios. In Cox model coefficients add; hazard ratios multiply. One final warning: there is a technical meaning of "frailty" in survival analysis that might lead to further confusion.
