Dear Greg,
Thanks for the new release. The decomposition of the SSQ is just what I need!

The C function getQ0 returns a non-positive covariance matrix and causes errors in arima()
Hi,
the function makeARIMA(), designed to construct some state space
representation of an ARIMA model, uses a C function called getQ0,
which can be found at the end of arima.c in R source files (library
stats). getQ0 takes two arguments, phi and theta, and returns the
covariance matrix of the state prediction error at time zero. The
reference for getQ0 (cited by help(arima)) is:

SSQ decomposition and contrasts with ANOVA
Dear R list,
Please, could someone help me with SSQ decomposition and contrasts.
Below my data, graphic, ANOVAs and my doubt:

Trouble obtaining results from a loop
#Hello,
#I have a question about obtaining results from a loop I have written.

no convergence using lme
Hi. I was wondering if anyone might have some suggestions about how I can
overcome a problem of "iteration limit reached without convergence" when
fitting a mixed effects model.
In this study:
Outcome is a measure of heart action
Age is continuous (in weeks)
Gender is Male or Female (0 or 1)
Genotype is Wild type or knockout (0 or 1)
Animal is the Animal ID as a factor

plot legend outside the grid
Thanks Bert for all the help. I got the legend figured out Friday but left early becoz of long weekend so didn't get a chance to reply.. I modified the plot margins a little bit and Here's what I finally had...

question related to multiple regression
Hi,
I am conducting an association analysis of genotype and a phenotype such as
cholesterol level as an outcome and the genotype as a regressor using
multiple linear regression. There are 3 possibilities for the genotype AA,
AG, GG. There are 5 people with the AA genotype, 100 with the AG genotype
and 900 with the GG genotype. I coded GG genotype as 1, AG as 2 and AA as 3
and the p-value for the

problems with character objects and calls to list()
Hi All,
I have a problem trying to get a set of columns recognised as a list
and can't work out how to do it despite trawling through the mailing
list archives, and docs.
A short example...

n <- 6
for(x in 1:n){
to.convert <- paste(to.convert, paste((2 * x) -1, (2 * x), sep=":"), sep=",")
}

NaNs in Nested Mixed Model
Dear R users,
I have a problem with something called "NaNs" in a nested mixed model.
The background is that I have studied the number of insect nymphs
emerging from replicated Willow genotypes in the field. I have 15
replicates each of 4 Willow genotypes belonging two 2 Willow species.
Now I want to elucidate the effect of Willow genotype on the number of
emerging nymphs. Previously I

Looping over groups
Hello,
My R skills are somewhere between novice and intermediary, and I am hoping that some of you very helpful forum members, whom I've seen work your magic on other peoples' problems/questions, can help me here.
I have a matrix with the following format:
(i) individual plants comprising many different genotype groups (i.e., a plant is genotype 1 or genotype 2 or genotype 3, etc). The

R-devel does not update the C++ returned variables
Thanks! I went through the online posts which supports the power of .Call
over .C. But my probably naive question is why does this work for my code
with R but not R-devel?
And another question is related to using .Call. Based on the manual page, I
do not need to change the function parameters when using .Call. So I can
run like this:
.Call("sppedUp", D, S, pD, pS, nrow(D), as.integer(N),

using facet_grid() from ggplot2 with additional text in labels
Hi
I am using ggplot2 at the moment and I must say it is definitely better
then ggplot - good work.
My problem is that I am using facet_grid() in the following way:
> p <- ggplot(ssq, aes(x=year, y=-log(ssq)))
> p + geom_point() + facet_grid(me*gi~cs*rz)
and it works nicely, except that I would like to have, in naddition to
the values of me, gi, cs and rz the name of the variable.

I was not sharing it on maling list because i thought that someone can use
all ideas i proposed in their GSOC proposal.
Surely i will contribute to xapian project.
sorry if that was against the rules
The algorithm is not developed by me but after having much research on
various clustering techniques.
I found that there is a new algorithm called CLUBS(Clustering Using Binary

Two factor ANOVA in lme
I want to specify a two-factor model in lme, which should be easy?
Here's what I have:
factor 1 - treatment FIXED (two levels)
factor 2 - genotype RANDOM (160 genotypes in total)
I need a model that tells me whether the treatment, genotype and
interaction terms are significant. I have been reading 'Mixed effects
models in S' but in all examples the random factor is not in the main
