Problema con un xml demasiado Grande
Hola, muy buenas,
Me bajé un archivo xml de la wikipedia en español. Al intentar abrirlo
en R el ordenador no es capaz, ya que pesa descomprimido 10 GB. De ese
xml solo me interesa un campo, el referente al texto del artículo.
¿Alguiém conoce alguna forma de cargar solo ese campo del xml en R sin
cargar el xml completo? La salida seria un archivo .txt, donde cada fila
fuera un artículo ó

Lógica Bayesiana con R
Hola, buenas a todos:
Me dispongo a empezar un proyecto con logística bayesiana y sé que hay
varios paquetes que puedo utilizar, arm, Bayelogit y MCMCpack. Me
preguntaba si alguien tiene experiencia con éstos paquetes y me pueda
decir cuál de ellos es mejor.
Además de esto quería saber si sabíais alguna bibliografía para
informarme mejor sobre lógica bayesiana, tengo algunas referencias,

Using matprod from array.c
Hi,
I was wondering if I could use the matprod function from array.c in my own C routine. I tried the following as a test
/* my_matprod.c */
# include <Rinternals.h> /* for REAL, SEXP etc */
# include <R_ext/Applic.h> /* array.c says need for dgemm */
/* following copied from array.c */
static void matprod(double *x, int nrx, int ncx,
double *y, int nry, int ncy, double *z)

Multiple language output - Correct in RGui, wrong in .txt after sink()
I have the following problem with outputting multilingual data to a file.
I get (except for Korean) what I expect as result in the RGui, but when I
use sink() to output to a text file loose the characters in the foreign
languages.
I post a small example below. Since I am not sure how well my email system

about MCMC pack again...
Hello, thank you very much for your previous answers about the C++ code.
I am interested in the application of the Gibbs Sampler in the IRT
models, so in the function MCMCirt1d and MCMCirtkd. I've found the C++
source codes, as you suggested, but I cannot find anything about the
Gibbs Sampler. All the files are for the Metropolis algorithm.
Maybe I am not able to read them very well, by the

memory leak in 3.3.1 rebalance?
I started rebalancing my 25x2 distributed-replicate volume two days ago.

http://gluster.org/community/documentation/index.php/High_Memory_Usage,
I tried "echo 2 > /proc/sys/vm/drop_caches". This had no effect on the
processes' memory usage. Some of the

R windows crash (PR#9426)
Full_Name: Robert Denham
Version: R-2.4.1
OS: Windows Xp
Submission from: (NULL) (61.88.57.1)
R gui exits without warning when I run a function which has an argument with a
default that is not found.
This was a result of an error in a function I wrote, but I thought that it
should exit more gracefully than it does. Here is an example:

ks.test not working?
Hi,
I am performing GEV analysis on temperature/precipitation data and want to use the ks.boot function but I am unsure of how to implement it using the pgev distribution.
For example:
ks.test(data,pgev,shape,location,scale)
ks.boot(data,(distribution parameters?),alternative="pgev",nboots=1000)
Any advice? Apologies in advance if I have used the wrong email address.

Muchas gracias por su tiempo.

Multiple deployments of same application using backgroundrb

I read that it was unnecesary and it will not work to have multiple
instances of backgroundrb for each of my deployments. I read that it was
