Hi folks, recently I was trying evaluation of some complex function having exactly same starting values as well as same algorithm in both R and .Net environment. However at the end point I notice that there are some differences in the reported figures from those two applications (as much as 0.10%). I feel this is basically due to consideration of different significance digits in handling floating

The pretty picture that I saw at: http://chartsgraphs.wordpress.com/2009/02/09/r-panel-chart-beats-excel-chart/#more-1096 inspired me to try something similar. The code that I wrote is: ------snipsnip--------------------------------------------------------------------- M <- structure(list(date = structure(c(13634, 13665, 13695, 13726, 13757, 13787, 13818, 13848, 13879, 13910, 13939, 13970,

Hello to the R world... I have some problems regarding a GLM - repeated measures analysis. I want to test overall differences between AgeClass and Treatment (between subject) with OpenR1+OpenR2+OpenR3 (repeated measures, within subject). The table looks kind like this: AgeClass Treatment OpenR1 OpenR2 OpenR3 1 1 0 0 12.63 1 1 12.67 3.83 45.67 1 1 38.46 65.38 75.21 1 1 14.46 0 17.96 1 2 27.83

Hi, In the code below I create a small data.frame (dat) and then cut it into different groups using CutList. The lists in CutList allow to me choose whatever columns I want from dat and allow me to cut it into any number of groups by changing the lists. It seems to work OK but when I'm done I have a variable number of data frames what I need to do further operations on and I don't know

hello, I'd like know how to sort a data frame in R for example how I should do to sort by Catholic with swiss data frame like below thanks Fertility Agriculture Examination Education Catholic Infant.Mortality Courtelary 80.2 17.0 15 12 9.96 22.2 Delemont 83.1 45.1 6 9 84.84 22.2

Hi I'm trying to setup a 3 node gluster, and am hitting huge performance bottlenecks. The 3 servers are connected over 10GB and glusterfs is set to create a 3 node replica. With a single VM performance was poor, but I could have lived with it. I tried to stress it by putting copies of a bunch of VMs on the servers and seeing what happened with parallel nodes.. network load never broke

Hi, So is the KVM or Vmware as the host(s)? I basically have the same setup ie 3 x 1TB "raid1" nodes and VMs, but 1gb networking. I do notice with vmware using NFS disk was pretty slow (40% of a single disk) but this was over 1gb networking which was clearly saturating. Hence I am moving to KVM to use glusterfs hoping for better performance and bonding, it will be interesting to see

I've been using parApply() in snow package for parallel computing with the following lines in R 2.8.1: library(snow) nNodes <- 4 cl <- makeCluster(nNodes, type = "SOCK") fm <- parApply(cl, myData, c(1,2), func1, ...) Since I have a Mac OS X (version 10.4.11) with two dual-core processors, I thought that I could run 4 simultaneous clusters. However with the 1st job

Subject says all. Timo, would you write something up where the world will find it? Also, it would be great if doveadm fts was covered in the doveadm manpage. Thanks, -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

Quick question. How important are these? Are the errors recoverable and not a big deal, or are they actually a problem? I see a few of these randomly over the course of the day.

Hi! I'm not sure is it the same as described by Andrew Lewis, this is whay i'm posting.

Hola buenas. al final corri el siguiente código en mi máquina de casa. El problema es que ha habido algún cambio en la librería lme4, que hace incompatible los nuevos objetos lmer con la funcioón pamer.fnc. En este tipo de situaciones imagino que lo propio sería ponerme en contacto con el autor o intentar corregir yo mismo el código o incluso ambas. ¿Es decortes escribir al autor reportandole el

Estimado Javier Villacampa Gonzáles Si una persona se toma el trabajo de desarrollar y compartir, como es el caso de R, seguramente conoce de problemas que tuvo que decidir mientras escibía el código, y estará agradecido porque hay gente que utiliza su aporte, su trabajo no fué a la nada, todo lo contrario. En mi caso un solo autor tuvo una respuesta negativa para con migo. Javier Marcuzzi

Javier, Creo que aquí aplica la ley de Linus que dice: "Dado un número suficientemente elevado de ojos, todos los errores se convierten en obvios". La persona que revisa y encuentra un error no necesariamente tiene que ser la misma que la que lo escribe. Una motivación muy importante al compartir un código es la de recibir los beneficios del control de calidad por parte de tus pares.

Gracias a todos por las recomendaciones. Ya me he puesto en contacto con el autor y le explicado donde esta el error. Es tan fácil como que han cambiado la estructura de los objetos tipos lmer desde la versión 2.15.3 con lo que su paquete dejo de funcionar. Por suerte la nueva estructura conserva por lo menos la parte necesaria para hacer sus funciones. Se localizar el fallo y como arreglarlo, lo

Hace unos meses os escribir para comunicaros que había un fallo en esta función. Como os prometí os comento la respuesta por si alguno está interesado en utilizar el paquete LMERconvenientsfucntions Dear Javier, The package has been updated and should work for you fine now. Note that function mcp.fnc does not return the fourth plot (dffits) anymore. We still have to figure out a way to compute

Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE

hi all, I want to move some routing tasks out of the router and into the controller. The goal is to make Merb feel less like mod_rewrite and give the user more control at the controller. The new Router is simple: it takes the path_info (not the whole request) then outputs a controller class and some parameters from the path matching. The rest of the routing would be done at the controller level.
