R help - May 2007 - Problem with lme4

Hi - I'm having a problem trying to use the function GLMM() from lme4. Here
is what happens:

 
> library(lme4)
Loading required package: Matrix

Loading required package: lattice
> f1 <- GLMM(success~yearF, data=quality, random=~1|bandnumb,
family=binomial, method=PQL)

Error: couldn't find function "GLMM"

 

I remember having used lme4 before, without any problem. Can someone help me
understanding what is wrong? I'm using R 2.2.1, could that be a problem? I
also tried installing lme4 again, and updating the package, with no success.

 

Thanks for your help,

 

Amelie

the lme4 function you want is probably lmer()
type
?lmer

btw. your R is very old we are at 2.5.0 ...

Hi all,

I want to develop a choice based questionnaire and I need to generate a set 
of choice tasks

The design is comprised of four attributes (5*3*3*3) with the following
5    price
3    brand
3    service
3    installation

I need to determine the minimum no of choice tasks which can be used to 
estimate main effects for each attribute and then actually generate these 
choice tasks to be included in the survey

SPSS has orthoplan but only generates these tasks for a traditional conjoint 
design, not for conjoint based choice tasks

A partial factorial design is what I had in mind .........................

Is there a package to be able to do this in R?

Many thanks Paul
