Error in lme4 0.999902344-0: "Object 'multResp' not found" ?
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
