[R] Using nlme and coxme (both!): Looking for workaround

[Dieter Menne]

I am trying to use nlme and coxme in one Sweave document. I have read the
thread in r-devel on the subject, 

http://markmail.org/thread/snchg6ynofrzbf2v

and nlme::fixef works, but I did not understand what workaround to use when
I am calling a function in a package that I do not want to change.

Dieter



library(nlme)
library(coxme) # hides fixef, among others

deplynestedforeingpackagefunction = function(x){
  # I do not want to change this function in another package
  fixef(x)
}

fit <- coxme(Surv(time, status) ~ age + (1|ph.ecog), lung) 
fixef(fit)

fm1 <- lme(distance ~ age, data = Orthodont)
nlme::fixef(fm1) # can use nlme::
# 
deplynestedforeingpackagefunction(fm1) #error
