Summary of the query: "update" does not work on a coxme object I ran into this bug myself 2 days ago -- I rarely use update() so hadn't encountered it before. The problem is that coxme breaks the formula into fixed and random portions, and this confuses the default method for formula.
Solution: add the following function: formula.coxme <- function(x, ...) x$call$formula This method will be included in my next update of coxme.
