setting value arg of pdSymm() in nlme
Dear All,
I wish to model random effects that have known between-group covariance
structure using the lme() function from library nlme. However, I have yet
to get even a simple example to work. No doubt this is because I am
confusing my syntax, but I would appreciate any guidance as to how. I have
studied Pinheiro & Bates carefully (though it's always possible I've

Function nlme::lme in Ubuntu (but not Win or OS X): "Non-positive definite approximate variance-covariance"
Dear all,
I am estimating a mixed-model in Ubuntu Raring (13.04¸ amd64), with the
code:
fm0 <- lme(rt ~ run + group * stim * cond,
random=list(
subj=pdSymm(~ 1 + run),
subj=pdSymm(~ 0 + stim)),
data=mydat1)
When I check the approximate variance-covariance matrix, I get:

understanding the verbose output in nlme
Hi
I have found some postings referring to the fact that one can try and
understand why a particular model is failing to solve/converge from the
verbose output one can generate when fitting a nonlinear mixed model. I am
trying to understand this output and have not been able to find out much:

manual recreation of varConstPower using new fixed effects variables in nlme
Hello, I am trying to design new variance structures
by using fixed effects variables in combination with
the VarPower function. That is, I would like to
create and evaluate my own variance function in the
data frame and then incorporate it into the model
using varPower, with value=.5.
As a start, I am trying to recreate the function of

error in nlme
I'm getting an error from nlme that has me stymied. I have a data set

indicate two levels of nesting, with 'set' nested within 'mrid'. I want to
fit the model:

Access denied from NT
Hi,
I have a problem in accessing samba server from NT
network neighbourhood. I can see the samba server icon
on neighbourhood. But while trying to access then it's
asking for user name & passowrd.
I am not using local user & password from unix box
rather it should be authenticated from NT PDC and
accordingly I have modified the smb.conf file. Here is
the sample of that.

share -
xcopy /d /e c:\somedir w:\somedir
xcopy /d /e w:\somedir c:\somedir
This should have the behavior of making the two directory
structures identical, with newer files on one overwriting older
or missing files on the other.
This only behaves as expected for about half the files. For some
files, Windows always wants to re-copy files to the Samba share.
I have looked at the files it wants to

Java?
I'd be interested in helping too. I'm pretty new, but I think that JNI
would be the easiest way to go. of course, never having done anything with
JNI, what do I know :)

using samba to serve the whole tree of home directories
I'm trying to use samba to serve a number of home
directories to other samba Linux clients on my
network.
ie. I have a set of client machines that want to use
the /home directory that my samba server will provide
I thought I could set up a share that goes something
like this
[homedirs]
path = /home
writable = true
On a client machine, I smbmount //myserver/homedirs

max. no of files(again)
Hello!
A good day to you all. we've recently had some
problems with samba (2.2.0) and sourcesafe. We had one
particular project with over 700 files on it, and
we've just recently encountered some problems with it,
i.e. "corrupted" files from sourcesafe.
i've read the archives, and someone mentioned that the
number is actually unlimited(or 6.4million at the very
least)...so

segfault with correlation structures in nlme
Hi out there,
I am trying to fit a species accumulation curve (increase in number of
species known vs. sampling effort) for multiple regions and several
bootstrap samples. The bootstrap samples represent different
arrangements of the actual sample sequence.
I fitted a series of nlme-models and everything seems OK, but since the
observations are correlated I tried to include some correlation

Hello all,
Here is my situation:
I have an existing linux box with 100+ users. This box
run various services. Users do not have shell access.
I have added samba to this box so users can share
files and access their files from Windows. Samba
installation and configuration went smoothly. Now, the
problem is, I need to create entries in smbpasswd for
these 100+ users.
How would I go about creating

lme unequal random-effects variances varIdent pdMat Pinheiro Bates nlme
How does one implement a likelihood-ratio test, to test whether the
variances of the random effects differ between two groups of subjects?
Suppose your data consist of repeated measures on subjects belonging to
two groups, say boys and girls, and you are fitting a linear mixed-effects
model for the response as a function of time. The within-subject errors
(residuals) have the same variance in

pdMat class in LME to mimic SAS proc mixed group option? Group-specific random slopes
I would like to be able to use lme to fit random effect models In which some but not all of the random effects are constrained to be independent. It seems as thought the pdMat options in lme are a promising avenue. However, none of the existing pdMat classes seem to allow what I want.
As a specific example, I would like to fit a random intercept/slope mixed model to longitudinal observations in
