lme4/Matrix: Call to .Call("mer_update_y"...) and LMEoptimize gives unexpected side effect...
Dear all
I want to compute Monte Carlo p-values in lmer-models based on sampled data sets. To speed up calculations, I've tried to use internal functions from the Matrix package (as suggested ealier on the list by Doug Bates).
So I did:
fm2 <- lmer(resistance ~ ET + position + (1|Grp), Semiconductor,method='ML')
simdata<-simulate(fm2,nsim=1)
ynew <- simdata[,1]

help in ar function
Dears Sirs
During my computational work I encountered unexpected behaviour when calling "ar" function.
I want to select the order p of the autoregressive approximation by AIC criterion and sometimes an error occurs.

lmer error: number of observations <= number of random effects
I am running a multilevel growth curve model to examine predictors of
social anhedonia (SA) trajectory through ages 12, 15 and 18. SA is a
continuous numeric variable. The age variable (Index1) has been coded as 0
for age 12, 1 for age 15 and 2 for age 18. I am currently using a time
varying predictor, stress (LSI), which was measured at ages 12, 15 and 18,
to examine whether trajectory/variation

anova function to test the difference between two coefficients in nlme package
Dear Dr. Bates, and R-help,
I've tried the anova function to test the difference between two
coefficients, as shown on page 225 of your book "Mixed Effects Models
in S and S-Plus (Statistics and Computing)".
When I type: anova( fm2BW.lme, L = c(TimeDiet2 = 1, TimeDiet3 = -1) )
I got the following error message:

lme4 install trouble
After upgrading to R 2.6.0, I'm having trouble running lmer:
model <- lmer(primed ~ log(dist.time)*role + 1|target.utt,
data=data.utts)
Error in UseMethod("as.logical") : no applicable method for "as.logical"
So I thought I'd upgrade lme4 to the latest version, but
unfortunately the compilation fails - perhaps there's a missing

error in display function of the ARM package
Hi,
I get the following error message when trying to use the display
function on the ARM package:
> display(model)
Error in .Internal(round(x, digits)) : no internal function "round"
Looks like some kind of mismatch between the ARM package and some
others? Can I somehow get around it? I have learned to like the display
function to print model summaries.

setHook and lattice
Hi,
I am trying to find a way to automate production of page numbers in plots
produced using the lattice package. To do this, I started playing around
with setHook which works fine with vanilla plot, but the hook 'plot.new'
doesn't appear to be relevant to the lattice package. I was wondering if
there is a alternative someone can suggest for use with the lattice package.

Another issue with the Matrix package.
Hi all,
I am encountering a strange issue with the Matrix package. I have just built
R-devel from source on my macbook pro, and I wonder if others can reproduce
this problem. I will give example code to go along:

Problem reading data in Rmetrics

Error in solve.default message using lme
Dear All,
I?m using lme to analyze a time series gene expression data. I don?t have
all animals in all times, the number of animals in each time is different
and I have lots of NA values.

R crash with modified lmer code
Hi all,
I've now got a problem with some modified lmer code (function lmer1
pasted at end) - I've made only three changes to the lmer code (marked),
and I'm not really looking for comments on this function, but would like
to know why execution of the following commands that use it almost
invariably (but not quite predictably) leads to the R session
terminating.

[R-sig-ME] lmer error: number of observations <= number of random effects
Dear Srinidhi,
You are trying to fit 1 random intercept and 2 random slopes per
individual, while you have at most 3 observations per individual. You
simply don't have enough data to fit the random slopes. Reduce the random
part to (1|ID).
Best regards,

plotting predicted curves with log scale in lattice
Hi,
I was taken off guard by the following behavior in a lattice plot.
I frequently want to add a predicted curve defined at more
points than in the formula expression of xyplot. There have
been numerous examples of how to do this on r-help, but I
still often struggle to make this work. I just realized that
specifying one of the axes on a log scale does not guarantee
that the added data for a

Error message in lmer

I try to run a bootstrap with lmer.
I often, but not always, get the error message:
Error in objective(.par, ...) :

In R-archives I came across some threads that treated this problem,
nevertheless they refer to lmer when using it with family = "binomial", so
