similar to: which en un data.frame de caracteres?

Hola a todos, Quería saber si alguien tiene un buen tutorial para el paquete data.table. Estoy levantando los micro datos del censo Uruguayo del 2011, con una maquina no muy buena, solo lo he logrado utilizando dicho paquete. Ahora no puedo hacer operaciones sencillas como contar los mayores de 18 años de edad por departamento. Bueno si alguien tiene un tutorial de dicho paquete o algún otro

Hola a todos: Debe de ser una tontería, pero no consigo saber porque la siguiente linea no devuelve la fecha actual: as.Date(as.numeric(Sys.time())) He hecho esa prueba porque no consigo pasar un numero convertido a partir de una fecha y modificado a fecha de nuevo. Gracias por adelantado. Un saludo, Alberto. [[alternative HTML version deleted]]

Hola a todos: Estoy intentando visualizar unos resultados de un programa en R de forma dinámica. Dichos resultados se pueden representar, básicamente, con un plano que gira sobre uno de sus ejes: para dar sensación de movimiento he utilizado la función rgl.clear(), ya que no encuentro los equivalentes en rgl de los parámetros add o new. El problema es que al limpiar la pantalla con rgl.clear la

¡Gracias Carlos, como siempre! No había caído en que podía hacer merge sobre el mismo data.frame merge(p,p,by.x="id",by.y="anterior",all=T)[,c(-6:-8)] Un saludo, Alberto El 5 de diciembre de 2013 13:22, Carlos J.

¡Hola a todos! Tengo el siguiente data.frame: p <- data.frame(id=c(1:6),cara=c(1,0,0,1,0,0),anterior=c(0,1,2,0,4,5),siguiente=c(2,3,0,5,6,0),superficie=c(1,2,0,1,2,0)) En realidad es muchísimo más grande, pero creo que las primeras filas servirán para explicar mi problema. El data.frame contiene los puntos de intersección entre fotones y superficies. Dichos puntos están identificados con el

Is there currently a way to get static profiling information for a program (e.g. an implementation of "Static Branch Frequency and Program Profile Analysis" by Wu and Larus, or something more recent) using an LLVM pass?

Hi all: I hope someone can help me with this "little" problem... I''m using a linux script to sub-divide my bandwidth (64kbit) into: 40kbit for VOIP, and the remaining 24kbit for http. So, the commands I''m using are: ============================================ #!/bin/bash # This script shapes "downloading" stuff # Initial qdisc tc qdisc add dev eth1

It's done at the MachineFunctionPass level as far as I can tell ( http://llvm.org/doxygen/classllvm_1_1LiveIntervals.html). I'd like something at the FunctionPass level.

Folks, I am terribly puzzled by an issue reported as bug 2381 [http://bugs.centos.org/view.php?id=2381] ? definitely an upstream bug, as it does the same under X/OS 5 and StartCom 5. Simply put: Hibernation fails with horrendous I/O errors after swsusp starts dumping to swap. What bugs me is that hibernating from the CentOS 5 LiveCD *works*!!! (on the same hardware) How could I investigate to

Ok. If it's at llvm ir level, it's very simple since everything is in SSA form. What are you trying to achieve though?

I had previously asked about R interfaces to various "other" visualization tools specifically lightweights for monitoring progress of various codes. I was working on this, https://github.com/mmarchywka/mjmdatascope but in the meantime found out that Paraview has an "in-situ" capability for similar objectives.

Is there an equivalent to LiveIntervals that works at the Function level? If not, is there anything that makes it difficult to implement compared to the MachineFunction version?

Dear list: I have a problem I cannot handle yet, and need to solve it as soon as possible. Would be very greatful with anybody who can help me.

Hola, Yo en vez de data.table, probaría con el paquete "*sqldf*" que tiene una sintaxis en sus queries más sencilla que la de data.table. Y en términos de volumen [1] y velocidad [2] de respuesta son bastante equivalentes.

I am not sure what you mean. Live interval analysis is done at the function level.
