(OT) Fourier coefficients.
This posting has nothing to do with R (except maybe that I am using R
very heavily in writing the paper to which the question pertains.) I
simply wish to draw upon the impressive knowledge and wisdom of the R
community.
Since this question is way off topic, if anybody has the urge to
reply, they should probably email me directly:

Bug in a couple of btrfs-progs components
Hi,
(I''m not a list member and may not see any responses to this)
I''ve been using btrfs on my Raspberry Pi. Yesterday I tried to use the
"btrfs scrub" function and, while the scrub started OK, I couldn''t run
"btrfs scrub status" to see what was happening. Whenever I ran it, I
just got the command help.
The same command on my x86 box worked OK.

MCLUST Covariance Parameterization.
Hello all (especially MCLUS users).
I'm trying to make use of the MCLUST package by C. Fraley and A. Raftery. My problem is trying to figure out how the (model) identifier (e.g, EII, VII, VVI, etc.) relates to the covariance matrix. The parameterization of the covariance matrix makes use of the method of decomposition in Banfield and Rraftery (1993) and Fraley and Raftery (2002) where

write_unbuffered -- Connection reset by peer
Dear all,
This is just a placeholder really - I've spent quite a lot of time
trying to track down the cause of a problem I'm seeing here, and
have eventually got an answer. Thought it might be useful to have
the solution googleable.
Obviously, if someone has better ideas, I'd welcome comments. Similarly,
if anyone wants detailed logs, tcpdump or strace output, I'd be happy

More mdct questions
Sorry for starting another topic, this is actually a reply to Segher's post
on Sun Oct 22 on the 'mdct question' topic. I wasn't subscribed properly
and so I didn't get email confirmation and thus can't add to that thread.
So Segher, if the equation is indeed what you say it is, then replacing
mdct_backward with this version should work, but it doesn't.

formula used by R to compute the t-values in a linear regression
Hello,
I was wondering if someone knows the formula used by the function lm to compute the t-values.
I am trying to implement a linear regression myself. Assuming that I have K variables, and N observations, the formula I am using is:
For the k-th variable, t-value= b_k/sigma_k
With b_k is the coefficient for the k-th variable, and sigma_k =(t(x) x )^(-1) _kk is its standard deviation.

Weighted median
Is there a weighted median function out there similar to weighted.mean()
but for medians? If not, I'll try implement or port it myself.
The need for a weighted median came from the following optimization
problem:
x* = arg_x min (a|x| + sum_{k=1}^n |x - b_k|)
where
a : is a *positive* real scalar
x : is a real scalar
n : is an integer
b_k: are negative and positive scalars

lmer(): specifying i.i.d random slopes for multiple covariates
Dear readers,
Is it possible to specify a model
y=X %*% beta + Z %*% b ; b=(b_1,..,b_k) and b_i~N(0,v^2) for i=1,..,k
that is, a model where the random slopes for different covariates are i.i.d., in lmer() and how?
In lme() one needs a constant grouping factor (e.g.: all=rep(1,n)) and would then specify:
lme(fixed= y~X, random= list(all=pdIdent(~Z-1)) ) ,
that?s how it's done in the

Verifying understanding of backup-dir vs compare-dest
Hello,
Say one starts with creating an archive
rsync work -> archive
and periodically (below, i = 1 to N) does
rsync --backup-dir=a_<i> work -> archive
and rsync --compare-dest=archive work -> b_<i>
Then suppose one wants to recover the work directory as it was at
time k.
Using the b_<i> directories, one would merely merge

mdct explanation
...as promised.
This describes the mdct used in my d.m.l patch. I think it is the
same as the Lee fast-dct.
I typed it in a kind of pseudo-TeX, 'cause the ascii art would
kill me. Hope you can read TeX source; if not, ask someone who
can to make a .ps/.gif/.whatever of the TeX output, and put it
on a webpage or something. I'm to lazy to do it (and besides, I
don't have access to TeX,

A logit question?
Hello dear r-gurus!
I have a question about the logit-model. I think I have misunderstood
something and I'm trying to find a bug from my code or even better from my
head. Any help is appreciated.
The question is shortly: why I'm not having same coefficients from the
logit-regression when using a link-function and an explicite transformation
of the dependent. Below some details.

Sort logfiles at rotation time
Hi,
I want to be certain that my apache and varnish logfiles are in strict
date order when rotated. I'd like to run a sort command against them
before they're compressed.
I've had a look at the logrotate man page, and it looks like I can use
a postrotate/endscript to do this. However, I can see any reference
in the documentation for how to operate on the file. All the examples

rotate of logfiles
Hello list.
This is not a life-threatening question, but still quite important for
debugging.
I have the following crontab :
15 0,8,12,17 * * * /usr/sbin/asterisk -rx 'logger rotate'
Because I have debug level 9, logfiles get quite large.
I notice that the rotation of the logfiles goes to plan, except at 17h15.
I currently have :

mdct question
Hi,
Can someone tell me which MDCT and invMDCT equation uses? I implemented the
invMDCT one given in
eusipco.corrected.ps file (handed out by Monty way back) and it produces
different time domain samples.
I tried both the FFT method and the slow way directly from the equation and
couldn't reproduce the results
from the original code. This leads me to believe that the forward

The data are measurements of salinity s and temperature t

If h is ignored, the for each p, there

Reading SAS version 8 data into R
Hi,
SAS transport files created with the xport engine in SAS can be read using read.xport. However, the xport engine only works with SAS version 6, and consequently long variable names are not allowed...
Can anyone tell me how to get SAS data (ver 8) into R (easily)?
Thanks in advance

Samba 2.2.2 and logfiles
I'm having trouble with the logging in Samba 2.2.2. I usually specify
the name of the logfile on the command line (e.g., "nmbd -D -l
/path/to/logfiles"). This used to work with Samba 2.2.1a but does not
work anymore with Samba 2.2.2. I could not find anything about changes
to the logging mechanisms in the 2.2.2 announcement, so I am wondering
what's wrong here. Specifying

Sweave/margin
Hi!
I am currently using Sweave for writing my bachelor thesis - and I have a
problem:
I am using a LaTeX style (report) with quite big margin spaces. The Sweave
generated LaTeX code "floats" into the margin - and it looks ugly. The text
is blocked and fine... then there comes some flattering code running over
the margin... and blocked text again.
Considering the LaTeX output, I guess
