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"

PlusV algorithm
Important (imho)! I found this site in the internet: http://www.plusv.org/ PlusV is an audio enhancement algorithm similar to SRB of Mp3Pro, but 1) better than SBR 2) Fully open-source It seems to me wise to include PlusV into new versions of Ogg Vorbis. P.S. what about some long-awaited features in Ogg Vorbis? 1) ability to turn off the frequency filter in the encoder (especially for high

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 I would like

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.

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 una variable de país (Countryb) y por otra (Q6). Además hay interacción entre la variable mobilityPDurG2 (es una variable 0,1, y 0 es la categoría de referencia) país. La categoría de referencia para país es "united kingdom". Mi duda surge si quiero calcular el hazard ratio para los que tienen un 1

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

cronbachs alpha - score.items(psych) vs reliability(Rcmdr)
Dear all, I like the way the Rcmdr package computes reliability. E.g reliability(cov(d[,c("q1", "q2", "q3", "q4", "q5", "q6")], use="complete.obs")) will not only give me the alpha score, but also for each variable, alpha.score if deleted. However - when writing scripts it's very tiresome to load the whole Rcmdr GUI just

SV: Speex modes
Thanks! Btw, have you tried using SBR-technology or similar with speech codecs? That might be a good idea I thought.. But I don't know if it produces as good quality with speech codecs as it does for music codecs. Do you know if there is any open source variant of SBR? /Pontus -----Ursprungligt meddelande----- Från: owner-speex-dev@xiph.org [mailto:owner-speex-dev@xiph.org]För Jean-Marc

Error starting Virtual Machine Manager: Failed to contact configuration server
I just updated and rebooted a VM host server which runs CentOS 6.5/x86_64. After rebooting, I can't start the virtual-manager due to the error: Error starting Virtual Machine Manager: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ [^]

Solr -> Xapian ?
Maybe a dumb question (I admit I haven't followed this thread very closely)... But why are you writing a new FTS driver? If squat allegedly does everything you need it to do, why don't you just take that plugin and fix it up to do what you need? That seems way easier than trying to create a FTS driver from scratch. michael > On January 7, 2019 at 7:05 AM Joan Moreau via dovecot

AACplus
Sorry for the crosspost but it's relevant to Vorbis and Icecast I believe. I'm seeing more and more streaming stations using AACplus, with many listeners being amazed at the sound quality. Most say that a 48kb/s sounds better than a 128kb/s MP3, which would put Ogg Vorbis at around 96kb/s IMO. That means only half the bitrate is required in AACplus compared to Ogg Vorbis for the same
