pvals.fnc() with language R does not work with R 2.10.1
Hi Everyone,
I am using R 2.10.1. lmer function works properly, however pvals.fnc
() does not despite the fact that I uploaded:
- library(lme4)
- library(coda)
- library(languageR)
This is the error message I get

Problem with aovlmer.fnc in languageR
Dear R list,
I have a recurring problem with the languageR package, specifically the
aovlmer.fnc function. When I try to run the following code (from R. H.
Baayen's textbook):
# Example 1:

latinsquare.lmer <- lmer(RT ~ SOA + (1 | Word) + (1 | Subject),
data = latinsquare)

pvals.fnc in lme4 and languageR
Hi everybody!
I was using the function pvals.fnc from package 'languageR' until April.
I do not know which version. Yesterday I updated all my packages
and tried to run my loop again. Now I get the following error message:

LanguageR pvals.fnc error message
Hi. I get an error message about not converging when I try and use the
pvals.fnc from the languageR library. The LMER analysis worked fine (See
below).
I am not an expert so I don't understand why the LMER worked but not the
pvals.fnc
Any help gratefully received.

Error running pvals.fnc in R version 2.13.0
Dear R-help:
I've been trying to run pvals.fnc in the newest version of R (2.13.0). The
function lmer worked fine, but when I tried to use pvals.fnc on the lmer
object, I got the following error:
"Error in pvals.fnc(elogr.subj.dys.sum.3x3.p, nsim = 10000) :

lmer for a binary dependent variable
Hi,
I am trying to use the lmer function from the lme4 package in R 2.8.0. to fit a generalized mixed-effects model for a dependent variable with a binomial distribution (for more info on my experiment, look below). However, I encounter a major problem: How is it possible to find the general test statistic and see the relative importance of the predictors? The methods which I found described in

p values con LMER
Hola Manuel
lo he tratado de hacer pero me sale
Error: unexpected string constante in:
"anova(a,as,test=Chisq")
no tengo ni idea de por qué...
Me resulta alucinante no poder contar ya con pvals.fnc. ¿Será imposible hacerse con ello?
Saludos,

p values con LMER
Hola a todos,
quería preguntaros un medio para obtener los valores p usando lmer. He tratado con pvals.fnc, que es lo que me habían recomendado, pero por algún motivo no está ya disponible etc.
Ésta es la función que tengo, pero da las "t", sin los valores p. Aunque Baayen indica que valores por encima de 2 son significativos necesito saber las p.
resultado = lmer(rt_ln ~ (fre_ln *

Mixed effects para factores y no para covariables. Guia y dudas
Hola buenas tras meses investigando como hacer anovas para factores con
efectos fijos y efectos aleatorios, he encontrado una serie de funciones
que satisfacen mis pretensiones y creo correctas en cierta medida. Me
gustaría compartirlas con vosotros con doble intención, la primera es
compartirla para que si otro se encuentra en esta situación que tenga el
trabajo hecho y la segunda es que sean

p values con LMER
Existe discusión sobre el uso de los p-valores en modelos mixtos. Como se
ha dicho antes, para mi lo más adecuado es comparar modelos mediante la
función anova. Por Internet se puede encontrar un buen libro de Douglas
Bates y en español, busca modelos mixtos con R de Luis Cayuela, enfocado
hacia ecología, pero está muy bien

pamer.fnc y la nueva versión de R
Hace unos meses os escribir para comunicaros que había un fallo en esta
función. Como os prometí os comento la respuesta por si alguno está
interesado en utilizar el paquete LMERconvenientsfucntions
Dear Javier,
The package has been updated and should work for you fine now. Note that
function mcp.fnc does not return the fourth plot (dffits) anymore. We still
have to figure out a way to compute

Hola buenas noches,
tengo un problema bastante gordo. ¿A alguno le ha dejado de funcionar las

que me precupa que no funcione el ejemplo de tutorial del autor.

LME with 2 factors with 3 levels each
Hello. I am new to R and new to linear mixed effects modeling. I am trying to model some data which has two factors. Each factor has three levels rather than continuous data. Specifically, we measured speech at Test 1, Test 2 and Test 3. We also had three groups of subjects: RepTP, RepNTP and NoRepNTP.
I am having a really hard time interpreting this data since all the examples I have seen

plot.logistic.fit.fnc
Hello All,
I am learning mixed effects logistic regression (lmer in lme4), and I am
having problems deciphering the goodness of fit function
plot.logistic.fit.fnc (languageR package). The only information I can find
is that this function plots observed proportions against mean predicted
probabilities for some binning of the data.
I have explored this function with several datasets, and have had

Last working lme4?
This evening I ran into the problem Chuck Clifton referred to in message 86
of Volume 71 Issue 9 of this list. That is, objects created by lmer change
after calling pvals.fnc on that lmer object when using lme4
version 0.999375-16 and 0.999375-28. This is somewhat troublesome. The bug

Correlated random effects: comparison unconditional vs. conditional GLMMs
In a GLMM, one compares the conditional model including covariates with the
unconditional model to see whether the conditional model fits the data
better.
(1) For my unconditional model, a different random effects term fits better
(independent random effects) than for my conditional model (correlated
random effects). Is this very uncommon, and how can this be explained? Can

reporting interactions of factors in linear mixed effects models
Hi,
I have a question about how I should report the results for a linear
mixed effects model where the model includes as predictors three
factors (facA, facB and facC), one of which (facA) interacts with the
other two. facA and facB have two levels and facC has 3 levels. There
are also several other continuous predictors (e.g. varA, varB, varC).
My mixed model is specified with the following

plot.logistic.fit.fnc
Hello,
I can not get the function plot.logistic.fit.fnc() working....it
returns "Error: could not find function "plot.logistic.fit.fnc"".
Do I need to upload as specific package first? I am trying to check
the fit of a mixed logistic model.
Also, any advice for checking the assumption of independence in a
mixed logistic model?
Many thanks in advance,

Problem with workspace loading after languageR use
Hello R,
To analyze multi-level data, I started learning and using lmer. So far
so wonderful. I then found some useful functions in package languageR.
But then the following problem ocurred: Whenever I load and use the
languageR package, then save the workspace - or quit R with saving the
workspace - I am unable to reload that workspace in a later session.
That is, R doesn't start at all
