CRAN (and crantastic) updates this week
New packages
------------
* apcluster (1.0.1)
Ulrich Bodenhofer
http://crantastic.org/packages/apcluster
The apcluster package implements Frey's and Dueck's Affinity
Propagation clustering in R. The algorithms are analogous to the
Matlab code published by Frey and Dueck.

when dimensionality is larger than the number of observations?
Hi, there:
Can anyone here kindly point some good reference or links on this topic?
Esp. some solutions from BioConductor or R, when dealing with
microarray-like, "fat" data?
thanks,

Is package "dr" appropriate for reducing the dimensionality of molecules conformational space ?
I anticipate lacking of prior experience with dimensionality reduction problems.
Some scientists concerned with drug discovery performed several steered Molecular Dynamics simulations of the
alanine-dipeptide molecule dragged by a radial force from an equilibrium conformation to another different equilibrium conformation.
They sampled at regular intervals 7 dihedral angles, 5 bending angles, and

operating on arrays of unknown dimensionality
Dear R-users,
I am looking for a way to assign to slices of arrays where dimensionality of the array is not a-priory known.
Specifically, I would like to be able to generalize the following example of dimensionality 2 to an arbitrary diminsionality:
In this example we create an array x, a smaller array y and then assign y to a slice of x.

LDA with previous PCA for dimensionality reduction
Dear all, not really a R question but:
If I want to check for the classification accuracy of a LDA with
previous PCA for dimensionality reduction by means of the LOOCV method:
Is it ok to do the PCA on the WHOLE dataset ONCE and then run the LDA
with the CV option set to TRUE (runs LOOCV)
-- OR--
do I need

Cannot allocate vector of size
Hola Rubén,
Totalmente de acuerdo con los consejos de Carlos. Ten en cuenta que
aunque R disponga de varios (bastantes) GB de memoria, algunos de los
objetos que va creando durante el proceso pueden consumirla por
completo. Es decir, que aunque tu ordenador tenga 64GB de RAM, es
posible que no queden 10 GB libres para almacenar un objeto (porque ya
hay demasiados objetos grandes en la

Classification of supernovae - a challenge
Hi all,
I thought I'd just point out, to those not having yet seen this, that
today there was a classification challenge posted for astronomy.
The web-site is http://www.hep.anl.gov/SNchallenge/
[I have nothing to do with this project so don't ask me any details!]
Basically the idea behind is that future surveys of the sky will turn
up a large number of supernovae (SNe). The

Cannot allocate vector of size
Yo creo que el problema principal está en betapart.core(), que crea y
mantiene simultáneamente en memoria varios objetos de alrededor de 1 Gb
que luego combina en una lista... Probablemente es entre las líneas el
código de betaper.core donde hay que ir eliminando objetos.
Saludos,
Marcelino

Antes de nada, me gustaría daros las gracias por toda vuestra ayuda.
He estado probando todo lo que me habéis dicho a la vez, y no hay manera, sigo teniendo el problema con el espacio.
En cuanto al tamaño de la base de datos, es más grande de lo que puse, me equivoqué y puse el tamaño de una base anterior con la que estuve trabajando, la actual tiene 36866 filas x 6500 columnas.

Cannot allocate vector of size
Hola a tod en s,
Soy nuevo en R-help-es, por lo que perdonadme si debería haber mandado este email a una sección en particular.
Quería consultaros un error que me aparece en R al hacer una matriz de disimilitud a partir de una tabla con 6000 columnas x 11000 filas. El mensaje que da R es "cannot allocate vector of size 10Gb", y me resulta extraño ya que tengo 64 Gb de RAM disponible.

[LLVMdev] DLX backend
So I thought I'd try to use the documentation on llvm backends to try to create a DLX backend. I think I've got most of the stuff for the .td files done but I've got some problems.
