Question about smbc_stat() and smbc_statvfs() in libsmbclient
I?ve been writing some code that uses libsmbclient to talk to SMB servers and I?m a little bit confused why ?smbc_stat()? sets the
st_uid & st_gid to the uid & gid of the process calling it, instead of trying to map the real owner & group of the path or setting it to -1:-1 if it can?t do that...
But there is probably some good reason for this?
Ie, if I call something like this:

Testing an interaction with a random effect in lmer
Hi,
I was hoping to get some advice regarding the testing of interactions, when one factor is modelled as a random effect...
I have a model with binomial error structure where the response variable is the proportion of time spent at the main sett (animals were tracked for 28 consecutive days in each season, and were recorded either at the main sett or an outlier sett, so the response variable is

[LLVMdev] [llvm-commits] [PATCH] BasicBlock Autovectorization Pass
Ralf, et al.,
Attached is the latest version of my autovectorization patch. llvmdev
has been CC'd (as had been suggested to me); this e-mail contains
additional benchmark results.
First, these are preliminary results because I did not do the things
necessary to make them real (explicitly quiet the machine, bind the
processes to one cpu, etc.). But they should be good enough for
discussion.

Cannot allocate large vectors (running out of memory?)
Hi.
As shown in the simplified example below, I'm having trouble allocating
memory for large vectors, even though it would appear that there is more
than enough memory available. That is, even with a memory limit of 1500 MB,
R 2.6.1 (Win) will allocate memory for a first vector of 285 MB, but not for
a second vector of the same size. Forcing garbage collection does not seem

Trace values in the function ca.jo()
Hi all R users,
I'm trying to replicate the same results that are given in a published
article after been granted
the same data that the authors use.
I'm having problems to determine the cointegration rank of my data set using
the Johnasen's trace test.
This trace test is already programmed in the package ur.ca and can be found
in the function

comparing groups of proportions
Hi, I initially posted this to the general R mailing list, but Bert Gunter
thought this may be a mixed model issue, so suggested me to post here.
I have a dataset that has 2 groups of subjects. For each subject in each group,
the response measured is the number of success (no.success) obatined with the
number of trials (no.trials). So a probability of success (prop.success) can be
computed as

lme: NaNs in hierarchical model
Dear R-users,
I'm somehow new to the topic of mixed models. I'd liked to simulate data
with a specific correlation-structure and analyze it with lme(). I have a
fixed effect (group) and a random effect (block):

Non-constancy of variances in mixed model.
Hi, I've been doing an experiment, measuring the dead-zone-diameters of
bacteria, when they've been grown with paper diffusion disks of
antimicrobial. There are two groups, or treatments - one is bacteria
that have been cultured in said antimicrobial for the past year, the
other group is of the same species, but lab stock and has not gone had
any prior contact with the antimicrobial.

Using subset to filter data table
I am having difficulty understanding how I would constrain a data set by
filtering out 'records' based on certain criteria.
Using SQL I could query using 'select * from my.data where LithClass in
('sand', 'clay')' or some such.
Using subset, there seem to be ghosts left behind (that is, all of the
LithClass *.Labels* remain after subset)

Question about smbc_stat() and smbc_statvfs() in libsmbclient
Re: the smbc_stat() returning wrong st_uid/st_gid: Yeah, I get why it?s difficult, but perhaps it should just return -1/-1 instead? It too is wrong but probably less confusing than seeing the local user?s uid/gid there??
Anyway, I?ve been working on a ?grand unifying :-)? ACL managing (CLI) tool since I got tired of all the different and quite frankly confusing/frustrating tools to manage ACL

Possible memory leak with R v.2.5.0
I'm working with a very large matrix ( 22k rows x 2k cols) of RNA
expression data with R v.2.5.0 on a RedHat Enterprise machine, x86_64

The relevant code is below, but I call a function that takes a cluster
of this data ( a list structure that contains a $rows elt which lists
the rows (genes ) in the cluster by ID, but not the actual data itself
