Subject: incorrect usage of glmer crashes R (PR#12375)
Full_Name: susscorfa
Version: 2.7.1
OS: ubuntu
Submission from: (NULL) (129.125.177.31)
Incorrect implementation of the grouping variable in the function glmer crashes
R
a small example:
require(lme4);
a<-data.frame(b=rpois(1000,10), c=gl(20,50), d=rnorm(1000,3), e=rnorm(1000,5),
f=rnorm(1000,2)+5);
glmer(b~d+f|c+(e), family=poisson, data=a)
It crashes R on debian linux (2 independant systems) as well as windows
The correct function usage is:
glmer(b~d+f+(e|c), family=poisson, data=a)
I suppose it should just eveluate as wrong usage of a function but should not
crash R
