R devel - Jun 2007 - error message from lmer

Hi,

I've begun to use the lme4 package, rather than nlme, for more flexibility
during modelling, and running the examples in lmer I receive this error
message:

---<---------------cut here---------------start-------------->---
R> (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
Error in printMer(object) : no slot of name "status" for this object
of class "table"

R> sessionInfo()
R version 2.5.1 RC (2007-06-25 r42057) 
x86_64-pc-linux-gnu 

locale:
LC_CTYPE=en_CA.UTF-8;LC_NUMERIC=C;LC_TIME=en_CA.UTF-8;LC_COLLATE=en_CA.UTF-8;LC_MONETARY=en_CA.UTF-8;LC_MESSAGES=en_CA.UTF-8;LC_PAPER=en_CA.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_CA.UTF-8;LC_IDENTIFICATION=C

attached base packages:
[1] "stats4"    "stats"     "graphics" 
"grDevices" "utils"     "datasets"
[7] "methods"   "base"     

other attached packages:
       lme4      Matrix rcompletion    rcompgen     lattice    diveMove 
"0.99875-2" "0.99875-2"     "0.1-2"   
"0.1-13"   "0.15-11"     "0.7-9"
    reshape 
    "0.7.4" 
---<---------------cut here---------------end---------------->---

Since this is happening in a fresh session, and with code from examples
help file, this looks like a potential bug.  Any thoughts?


Cheers,

I can't reproduce this without knowing what is in your startup files: it 
should work with --vanilla, so please try that and try to eliminate 
whatever is in your .Rprofile etc that is causing the problem.

Incidentally, using rcompletion is counterproductive in R 2.5.1 RC: the 
base functionality using rcompgen is a more sophisticated version.
