Subject: coxme: model simplification using LR-test?
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.
