similar to: Competiciín de classificación!!! Fwd: [R] 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

Buenas, tengo 30 000 000 de datos, y el R no me deja trabajar, como podria corregir eso problema para trabajar con los 30 000 000, mintras es estoy trabajando cada 1 000 000 pero no es igual. Espero puedan ayudarme saludos -- Manuel Bonilla

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

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 El 22/12/2015 a las 18:26, Carlos J.

Estimados todos: Me es grato escribir a esta lista de ayuda para R, ya que comparto 100% la filosofía de Software libre en especial software en Estadística ya que es la carrera que estoy siguiendo. El motivo de este mensaje es por un par de dudas que no pude resolver: 1. He utilizado las funciones para realizar pruebas de normalidad (kolmogorov-smirnov, cuando n>50) y (Shapiro, cuando

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. He seguido todas

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.

Hi! I've been tearing my hair out trying to get DOS file attributes to work with Samba. Basically, I have it all set up so the user mbolingbroke (me) can write to this Supernova Backup share I have - this all works fine. However, since this is going to backup my Windows machine I want to preserve the file attributes. To this end, I've set up mapping of the attributess using "map

So I am compling the newest release of samba 3.0.14a on Solaris 2.8. I can get it to compile but I don't get all the built in modules that I should and smbd when fired up bombs out with something like, ------- derek@supernova:/opt/UMsmb/sbin# ./smbd -c /etc/samba/smb.conf -i smbd version 3.0.14a started.

For all these patches I'd say: testers are welcome. The first three patches seem good enough to push as we speak IMHO (so if you agree, go ahead!), whereas for the fourth I don't know if this is the desired way to fix. The result of these four patches is that NV34 gives a nearly-correct desktop experience, where only some fading animations appear broken. It's quite useable now! [1/4]:

Here's our testcase: #include <stdio.h> struct flags { unsigned frog: 1; unsigned foo : 1; unsigned bar : 1; unsigned bat : 1; unsigned baz : 1; unsigned bam : 1; }; int main() { struct flags flags; flags.bar = 1; flags.foo = 1; if (flags.foo == 1) { printf("Pass\n"); return 0; } else {

Hello, I'm just letting everyone know that I've begun the preliminary part of putting together a working comment system. I have a few idea's on how to implement this system. 1. What I would like to do is grab the General and Input SDK's for Winamp first. Then I would like to add to our existing Winamp plug-in the ability to simply add comments via the built in ID tag

Hello experts, I?ll try and keep this brief but detailed (if that?s possible.). I?m sure I don?t understand the technologies sufficiently but I believe I?m seeing counter-intuitive behavior with my Samba 3 setup. What I want is nice, tight Win 2K3 security. What I?ve got is ADS integration, including domain user authentication using winbind, but I can?t get the security level right. Problem

Hi, I would like to have lineplot.CI and barplot.CI to actually plot confidence intervals , instead of standard error. I understand I have to use the ci.fun option, but I'm not quite sure how. Like this : > qt(0.975,df=n-1)*s/sqrt(n) but how can I apply it to visualize the length of the student's T confidence intervals rather than the stdandard error of the plotted means

I hope that someone can help me with this: I hav always used Samba by installing the binaries. That has worked well. But now I need the SSL-option - so I have to install it from the bottom. I use redhad 6.0 - and samba 2.0.6. First I removed the rpm of the existing installation(and deleted the smb.conf in /etc). Then I gunziped/untared the file in tmp. In the source directory I did the

Hello! I have been using Samba for 2,5 years now. I have had the same problem since I started - I can not connect the Samba server from a W98 pc when the server security level is set to USER. So I have dropped security and use SHARE instead. I can see the share from the Window-client, but when I try to double click i get an error message saying: "Write networkpassword: , Resourse:
