New versions of Matrix and lme4 packages for R-2.4.0
Versions 0.9975-1 of the Matrix and lme4 packages will soon be available on
CRAN for use with R version 2.4.0 or later.
Purpose of the packages:
The Matrix package provides S4 classes and methods for sparse
and dense matrices. The lme4 package provides functions for fitting
and assessing linear or generalized linear mixed effects models (also
called multilevel models). Like the Matrix package,

Incompatability of lme4 and Matrix packages
I just installed R 2.4 on a windows machine and installed the lme4 package
version 0.9975-1. Unfortunately this version requires the 0.9975-2 version of
the Matrix package which I cannot seem to find. It seems the newest version I
can find is 0.9975-1. Is there somewhere I could find this newer version.

Problems installing lme4 on Ubuntu
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
While I'm not an R expert, I have used R on Windows XP. Now I've moved
to Ubuntu (Intrepid), and I'm trying to configure R to work with the
Gelman and Hill _Data Analysis Using Regression and
Multilevel/Hierarchical Models_. So far, it's not working.
I start by following the instructions for installing arm and BRugs at

[SPAM] - Re: How to assess significance of random effect in lme4 - Bayesian Filter detected spam
Actually, I re-read the post and think it needs clarification. We may
both be right. If the question is "I am building a model and want to
know if I should retain this random effect?" (or something like that)
then the LRT should be used to compare the fitted model against another
model. This would be accomplished via anova().
In other multilevel programs, the variance components are

lme4 - higher level
Hello all,
I just started working with the lme4 package to estimate a multilevel
logistic regression and am planning to use this package for a
cross-classification / multiple-membership model. I haven't found many
worked examples and am trying to figure out how to add variables to the
higher-level part of the model. Consider the following example:
test.1 <- lmer(y ~ b1 + b2 + b3 +

lme4 and Variable level detection
I am making a little GUI for lme4, and I was wondering if there is a function
that automatically detects on which level every variable exists.
Furtheremore I got kind of confused about what a random effects model
actually calculates.
I have some experience with commercial software packages for multilevel
analysis, like HLM6, and I was surprised that lme4 does not require the user
to specify the

lme4 and function 'cholmod_start' not provided by package 'Matrix' / Ubuntu
Hello all,
Using Ubuntu 9.04 and R 2.8.1.
For a project I need to use the Zelig package, which in turn wants to
use the lme4 package. When trying to use Zelig and it tries to its required
packages I get the following error message.

New versions of Matrix and lme4 packages
I have uploaded version 0.96-1 of both Matrix and lme4 to CRAN. The
source package should migrate to CRAN over the weekend and binary
packages should be available some time next week.
As for previous releases, the versions of these two packages are
interdependent. The lme4 package requires Matrix_0.96-1 or later but
we cannot enforce the other dependency. Please remember that if you

reliability of the level-1 random coefficients (lme4)
Hello everyone,
I want to estimate the reliability *of the level*-*1 random coefficients
(the one *reported in the HLM output) using the software R. Does anyone know
how to get this statistic from R?
I'm using the function "lmer" of the package "lme4" to estimate multilevel
models.
I tried to use the formula but I can't find specific information such as the

CRAN versions of lme4/Matrix don't appear to work with R 2.1.1
I am currently using R 2.1.1 under Windows and I do not seem to be able
to load the current versions of lme4/Matrix. I have run
'update.packages.' I understand this is still experimental software but
I would like access to a working version.
Thanks.

New version of lme4 and new mailing list R-SIG-mixed-models
Version 0.9975-11 of the lme4 package has been uploaded to CRAN. The
source package should be available on the mirrors in a day or two and
binary packages should follow soon after.
There are several changes in this release of the package. The most
important is the availability of a development version of lmer called,
for the time being, lmer2. At present lmer2 only fits linear mixed
models.

lme4/lmer: P-Values from mcmc samples or chi2-tests?
Dear R users,
I have now tried out several options of obtaining p-values for
(quasi)poisson lmer models, including Markov-chain Monte Carlo sampling
and single-term deletions with subsequent chi-square tests (although I
am aware that the latter may be problematic).
However, I encountered several problems that can be classified as
(1) the quasipoisson lmer model does not give p-values when

Sobel's test for mediation and lme4/nlme
Hello,
Any advice or pointers for implementing Sobel's test for mediation in
2-level model setting? For fitting the hierarchical models, I am using
"lme4" but could also revert to "nlme" since it is a relatively simple
varying intercept model and they yield identical estimates. I apologize for
this is an R question with an embedded statistical question.

New Matrix and lme4: Must reinstall lme4 if got new Matrix
We have released to CRAN a new version of the (recommended)
package Matrix, and of package lme4 yesterday.
Anyone who gets the new version of Matrix *MUST* re-install lme4
-- if (s)he is using lme4 at all. Technical details about that further below.
The fact that yesterday's version number of Matrix is 0.9995875-2,
indicates that Matrix' version is indeed approaching 1.0 (*),
