Bootstrap lmekin model
Hi,I use the 'lmekin' model of the 'kinship' package of R in order to estimate heritability. I want to estimate the confidence interval of the variance coefficient and so I should use a bootstrap simulation. The pedigree file has 1386 subjects so I create a kinship matrix [1386*1386].This is the code of R I use:
kfit2 <- lmekin(IT~1+AGE +(1|ID), dati1,

Fixed heritability in an lme model
Hi R help,
I wanted to set a fixed heritability for the object "Trait" left of ~
operator. Is this possible using lme, or would I need to use something
like gls?
This is the model line contained within a function;
lme.out <- summary(lme(Trait ~ genotype, random = ~1|sire,
weights=~number, na.action="na.omit"))
Many thanks for any help.

problem in asreml function in wgaim package
Dear R users,
I am trying to use "wgaim" package for QTL analysis using mixed model approach. But i am stuck with "asreml" function while using "wgaim" package.
Do i need a separate package to activate "asreml" function beside "wgaim" package ?
If so, i tried to download "Asreml-R" package (i guess this is right package

Mixed-effects models / heterogeneous covariances
Dear R-list,
maybe someone can help me with the following mixed-effects models
problem, as I am unable to figure it out with the 'nlme-bible'.
I would like to fit (in R, obviously) a so-called animal model (google
e. g. "Heritability and genetic constraints of life-history" by Pettay
et al.) to estimate the variance component that is due to genetic
effects. The covariances of

Between-group variance from ANOVA
I'm trying also to understand how to get the between-group variance out of a
one-way ANOVA, but I'm beginning to think that in a sense, the variance does
not exist. Emma said:
*The model is response(i,j)= group(i)+ error(i,j)*
Yes, if by group(i) you mean intercept + coefficient[i].
*we assume that group~N(0,P^2) and error~N(0,sigma^2) *
Only the error is assumed to be a random

nlme error message
Dear Friends,
I am seeking for any help on an error message in lme
functions. I use mixed model to analyze a data with
compound symmetric correlation structure. But I get an
error message: "Error in corMatrix.corCompSymm(object) :
NA/NaN/Inf in foreign function call (arg 1)". If I change
the correlation structure to corAR1, then no error. I have
no clue how to solve this problem.

Multidimensional scaling and distance matrices
Dear All,
I am in the somewhat unfortunate position of having to reproduce the
results previously obtained from (non-metric?) MDS on a "kinship" matrix
using Statistica. A kinship matrix measures affinity between groups, and
has its maximum values on the diagonal.
Apparently, starting with a nxn kinship matrix, all it was needed to do
was to feed it to Statistica flagging that the

Security issue
Is there a way to restrict connection to my asterisk server to users based
on their IP addresses, and not just password. I have some hackers who
connect to my server to make illegitimate solicitation calls to people. I
had to shutdown the server for now until I find a solution. ANY HELP?
Thanks.

My Switch is being attacked using sip scanner tool (Service Abuse Attack)
An attacker is scanning my Asterisk Switch to gain illegitimate access to
VoIP call functionality.
Using a sip scanning tool, *it* sends REGISTERs with random identities. And
when it discovers one identity subscribed in my switch, it tries to
authenticate with random passwords using this user name.
For the moment, I have replaced this account. And also blocked the IP it has
used but each time

Tidiest way of modifying S4 classes?
I wish to make modifications to the plot.pedigree function in the
kinship package. My attempts to contact the maintainer have been
unsuccessful, but my question is general, so specifics of the kinship
package might not be an issue.
My first attempt was to make a new function Plot.pedigree in the
.GlobalEnv which mostly achieved what I wanted to. However, I'm sure
that's not the tidiest

commands overwritten
Hi,
I am often re-use commands in R by using the arrows to retype them and modify for the new needs. This way, I don't need to write commands again, and I can modify the command by inserting/deleting/re-writing the command. Today, suddenly, re-writing change the commands as the "insert" function does in Word. for example - if I am standing in the middle of

Random Coefficients using coxme
Hello, I was hoping someone could answer a question for me that may
either be statistical or script related. I don't come from a statistics
background, so I am not positive if I am using the correct nomenclature
or even the correct procedure. Is it possible to model "random
coefficients" in a mixed effects cox-regression using coxme from the
Kinship package? For example, using

'plm'/'kinship' package on Debian Etch?
Hi Folks,
Has anyone got a compiled binary of the package 'plm'
and/or of the package 'kinship' for Debian Etch?
I'm asking because I'd like to install 'plm', but have
failed because it depends on 'kinship', and 'kinship'
refuses to compile on my Debian Etch.
The underlying reason is the Debian refuses to allow me
