Dear Brian,

thanks a lot for your advice.

this does not work.

this works, if I load the languageR library before.

this works unconditionally. Including that line in a local .RProfile 
file, basically solves the problem.

A typical session would look like this (using example data from Hox(2002)):

# from Hox (2002)
hoxpop <- 
read.table("http://www.ruediger-pfister.de/download/popular.dat", 
header=TRUE)
hoxpop$PUPIL <- factor(hoxpop$PUPIL)
hoxpop$SCHOOL <- factor(hoxpop$SCHOOL)
hoxpop$SEX <- factor(hoxpop$SEX)

# load languageR
library(languageR)

# do some analyses ...

# save the workspace
save.image("D:\\statistics\\MultilevelAnalysis\\lm.RData")


After quitting R, the workspace "lm.RData" will not reload.
(this workspace can be downloaded here: 
http://www.ruediger-pfister.de/Downloads/lmRData.zip)
