[R-sig-ME] Error in lme4 0.999902344-0: "Object 'multResp' not found" ?

[Bertolt Meyer]

Dear list,

The simplest random intercept model that I try to fit with the newest version of lme4 (0.999902344-0) throws an "Object 'multResp' not found" error on my Mac (Mac OSX 10.7.3, German R 2.15.0). Here is a reproducible example:

install.packages(c("minqa", "Rcpp"))
install.packages("lme4", repos="http://lme4.r-forge.r-project.org/repos")
library(lme4)

my_data <- read.csv("http://dl.dropbox.com/u/5384027/my_data.csv")
my_data$group <- as.factor(my_data$group)

# the data set consists of 97 four-person teams
# with two variables x and y observed on the individual
# level in each team

head(my_data)
#   X group        y          x
# 1 1     1 2.914286  -8.170984
# 2 2     1 2.746269 -13.504318
# 3 3     1 3.171429  -1.504318
# 4 4     1 2.978723  -4.837651
# 5 5     2 2.928571  -8.170984
# 6 6     2 2.987013   8.495682

mlmodel1_ri <- lmer(y ~ x + (1 | group), data = my_data)

# Fehler in lmer(y ~ x + (1 | group), data = my_data) : 
#   Objekt 'multResp' nicht gefunden

Does anyone know how to fix this?

Greetings,
Bertolt
