reshape is re-ordering my variables
Is it an undocumented (at least I missed it if it's documented) feature
of the reshape function to do numeric variables followed by character?
I ask because that seems to be the case below.
> str(rcw)
'data.frame': 23 obs. of 21 variables:
$ ICU : int 1 18 17 9 22 19 6 16 25 26 ...
$ Q6.RC.1 : chr "SM" "JF" "IW"

the "union" of several data frame rows
Hi,
I have a question about how to obtain the union of several data frame
rows. I'm trying to create a common key for several tests composed of
different items. Here is a small scale version of the problem. These
are keys for 4 different tests, not all mutually exclusive:
id q1 q2 q3 q4 q5 q6
1 A C
2 B D
3 A D B
4 C D B D

Bit Rate Peeling Quality
Hi All,
Let me ask this question of the group: When bit rate peeling becomes
available, how will the quality of the peeled Vorbis file compare to a
file encoded at the target quality directly from the original?
So, for:
a.wav --> b.ogg (at q6) --> c.ogg (at q2)
a.wav --------------------> d.ogg (at q2)
how are c.ogg and d.ogg likely to compare in terms of audio

opus-codec.org/comparison: Mono or Stereo?
Looking at the Opus comparison page[1], I can't figure out whether the
Opus/AAC/Vorbis/MP3 lines are meant to imply a mono or stereo
encoding. Could someone please update the caption to clarify this?
The single dot for G.711 is clearly mono, but for stereo music, are
the codecs at the top meant to converge near 128 kbps, or 256 kbps?

new flags in Maildir files
Sorry if this is a dumb question:
I migrated my third system from courier to dovecot. My previous two
were MacOSX the third is FreeBSD 6.
I noticed (because of an rsync process taking longer than usual...)
that on FreeBSD the message files have, most of them at least, gained
extra suffix letters (in the range a-h I'd say) that I do not see
(mostly if not at all) on my MacOS systems. I

libreadanything ?
Is there a library that decodes any file format ? I need a
lib to decode ogg-vorbis (of course) and also wavs, mp3s,
flac... Using several different libs is not a good
solution. I don't like to use a lot of different APIs
to do the same thing with different file formats.

Interpretación de coeficientes en un cox proportional hazards con variable strata
Buenas.
Abajo pongo la salida de un modelo de cox , dónde he estratificado por

La categoría de referencia para país es "united kingdom".

[LLVMdev] How to register a new LLVM backend
Hi,
I'm developing a very basic new LLVM backend for a RISC machine (named
Risco), based on the existing Sparc and Mips backends and the main tutorial
[1]. I'm having trouble registering the backend so the main tools can see
it.
My project code is outside the source tree, and I've altered the Makefile to
generate a shared library for the backend (libLLVMRiscoCodeGen.so). I've

Buying Vorbis Music
('binary' encoding is not supported, stored as-is)
Hello,
I don't know if you knew that there's a russian site where you can buy your
music in Ogg Vorbis.
There are many albums where you can decide what Codec (MP3, AAC, WMA, Vorbis,
MP+) and Bitrate (or quality for Ogg) should be used to encode and download the
files encoded specifically for you.
The prices are somewhat low.

[ARM] Register pressure with -mthumb forces register reload before each call
If I'm understanding what's going on in this test correctly, what's happening is:
* ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize
* In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6)
* The function has three arguments, so those three plus the register we need to hold the

%d does not expand to domain
Hello, dovecot-1.1.7 on FreeBSD 7.1.
Usernames have dot in them (like uname.example for a user in
example.com).
in dovecot.conf I have:
mail_location: maildir:/userhomes/maildirs/%d/%n/Maildir
and for authentication:
username_format: %Ln
In the client, tried with CONE and Mail.app, I put the username as:

So, the authentication works fine, as it extracts

extlinux.conf not found
Hello,
I noticed the following behavior of extlinux 4.05:
I created an ext3 filesystem on the first (primary and active) partition
of a usb stick. I mounted it at /mnt/. Then I copied to /mnt/ldlinux.sys
the ldlinux.sys found in the syslinux 4.05 archive and I created a basic

Then I ran "extlinux -i /mnt/" and rebooted on the usb stick. I got

No, I haven't,
and as I may not address this bug further myself (in the near
future), it may be best if you file a formal report.

Tiger compatibility

Before I go any further about OSX creation dates etc. I just
discovered that the pre5 release doesn't work on OSX Tiger. I got this
message in the rsync progress:

Reason: Incompatible library version: rsync requires version 7.0.0
or later, but libiconv.2.dylib provides version 5.0.0

[PATCH 0/5] ARM NEON optimization for samplerate converter
From: Jyri Sarha <jsarha at ti.com>
I optimized Speex resampler for NEON capable ARM CPUs. The first patch
should speed up resampling on any platform that can spare the
increased memory usage. It would be nice to have these merged to the
master branch. Please let me know if there is anything I can do to
help the the merge. The patches have been rebased on top of master

migration and conversion from courier
Dear all,
back in January I posted about migration from courier and in
particular on the script courier-dovecot-migrate.pl.
That script had a bug on BSD (or should I say not-Linux?) type
systems*. On FreeBSD (6.1) and MacOSX (10.5) it appended a lot of
binary garbage at the end of dovecot-keywords files.
On a couple of systems I had not actually run the script with the --
convert option,
