Nested For loops
Dear R experts,
Might be very simple question to ask but would be insightful. As the same story of nested "for loops". following is the code that I am using to get the autocorrelation function of the sample data. I have tried to get rid of for loops but since I am touching R after such a long time that I need to practice more but I need help to revive my skills. I know that apply() or

cpu load on centOS 4.4
Hello all,
I've installed samba on pretty basic install on centos 4.4. I'm running
a P4 2.8Ghz, 1G Ram, Raid 5 SATA-2 disks running on both a 3ware and
Highpoint Rocket raid (this is going to get swapped out for a 3ware card
soon). When users copy files from a mac os x client I'm seeing the cpu
load avg (in top) get up to 7. These copies included 150+Gigs of lots

EM algorithm to find MLE of coeff in mixed effects model
I have a general question about coefficients estimation of the mixed model.
I simulated a very basic model: Y|b=X*\beta+Z*b +\sigma^2* diag(ni);
b follows
N(0,\psi) #i.e. bivariate normal
where b is the latent variable, Z and X are ni*2 design matrices, sigma is
the error variance,
Y are longitudinal data, i.e. there are ni

Feature requests for princomp(.) : Allow cor() specifications
(all in subject).
If I want to do a PC analysis in a situation with missing data,
I may want to have same flexibility as with "cor(.)",
e.g., I may want
princomp(x, ..., use.obs = "pairwise.complete")
Actually, I may want even more flexibility.
Currently,

Inconsistencies in subassignment (PR#7210)
I have made the 3-d case do the same as the vector case, which is what the
C code clearly intended (a goto label was in the wrong place).
This leaves the bigger question of the right thing to do. I note that data
frames give an error when any indices are NA.

Codificación UTF-8 en un Mc
Hola, Emilio
Muchas gracias por la respuesta. El problema es que la otra persona no
sabe nada de R, e instalarle RStudio va a ser casi peor.
Además, parece que el origen es que tiene su Mac con configuración USA
por un tema de correos y fechas; así que creo que lo que necesitaría es
algo que cambie solo la configuración de la sesión de R a UTF-8 o algo
parecido.
Quizás no es posible ....

Normalidad para datos multivariados
Hola! Estoy teniendo un problema para testar la normalidad y la homogeneidad de varianzas para mi modelo de manova
Es este mi modelo: m1<-manova(cbind(pred,fit,oniv)~tratamento/parcela+bloco,data.vegetacao)
Aparte de tener tres variables respuestas (predador, fitófago, omnívoro), también es un diseño anidado.
Alguien sabría responder esto? Gracias!

debugging T.38 issues
Hello list,
We're currently facing some issues concerning T.38 gateway faxing.
This is a device used almost exclusively for receiving faxes. Calls
are incoming to asterisk on a SIP trunk (sangoma netborder) using
G711A. Gateway mode is activated in the asterisk dialplan towards a
Cisco SPA 112 running firmware 1.3.5. We are using asterisk 1.8.13.0

PJSIP / T.38 - Asterisk not passing on v21 preamble and data
Dear list,
happy new year!
I am still trying to make T.38 work. In the meantime, I have upgraded to Asterisk 13.1.0, and I am using the most recent PJSIP library (compiling that stuff myself). My local fax software is capable of T.38, as is my ITSP; Asterisk sits in the middle, of course. Asterisk is in the same private subnet as the local fax software and talks to the ITSP through a NAT'd

Problems receiving some faxes in T.38
Hello,
We have been working with the ReceiveFax application for some weeks now in
order to receive faxes in T.38 and it works fairly well, but there are some
faxes that for some reason we are not able to receive correctly.
The asterisk version we are using is 1.6.0.6 with spandsp-0.0.5pre4 and the
asterisk machine is behind a CISCO mediaGW to be able to communicate with
the PSTN.

flac-1.1.1 completely broken on linux/ppc and on macosx if built with the standard toolchain (not xcode)
Sadly the latest optimization broke completely everything.
The asm code isn't gas compliant. the libFLAC linker script has a typo,
disabling the asm optimization and/or altivec won't let a correct build
anyway.
Instant fixes for the asm stuff:
