Estimados, tengo el siguiente problema: estoy trabajando con un data.frame que tiene 892 filas y 9 columnas, el cual adjunto para que puedan probar. Cuando consulto por las filas que cumplen una cierta condicion, por ejemplo, ... graph[graph$NCar==c("160s"),] obtengo el siguiente conjunto de datos: sol con dia NCar NIns isom area rep tipo 1 con 0.001 1 160s 0 s

Me funciono perfecto, muchas gracias Carlos ... si no es mucha la molestia, alguien podria explicarme la diferencia tecnica entre ambos signos, y porque == produce el resultado que produce ? en que casos deberia usar == y en que casos %in% ... cual es el significado de cada uno ? Disculpen que no me conforme solo con obtener el resultado adecuado, es solo que no me suena logico que == no

Hola, ¿qué tal? No uses == sino %in%. Un saludo, Carlos J.

Estimada comunidad, tengo el siguiente problema: Un data.frame con muchas filas de las que debo eliminar aquellas que cumplen varios criterios al mismo tiempo. Por ejemplo este data.frame: sol con dia NCar NIns isom area rep tipo 1 con 0.001 1 160s 0 s 6.083543e-01 1 2 con 0.001 1 161c 1 c 1.391274e-03 1 <NA> 3 con 0.001 1 161c 1 c

Hola de nuevo. Leí mal. Si vas a eliminar esas filas, entonces usa: sqldf("select * from graph where sol!='lim' and dia!=2") En el correo anterior seleccioné precisamente a esas descartando a las demás. Culpa de mis anteojos... jeje. On Fri, Jul 12, 2013 at 5:20 PM, Freddy Omar López Quintero < freddy.vate01@gmail.com> wrote: > ​Hola.​ > > >> Tengo que

Cuando utilizas "==" estás comparando el vector "graph$NCar" (longitud 892) con otro de longitud 2: c("160s","180s"). Es decir, comparas el primer valor de "graph$NCar" con el primer valor de c("160s","180s"), el segundo valor de "graph$NCar" con el segundo valor de c("160s","180s"), el tercer valor

...(srcdir)/$(@D) \ -I$(srcdir)/../include @INCINTL@ 4. It is worth mentioning that there is a subtle interaction with (my particular version of) make. In some cases make should be replacing $(@D) with '.', but instead replaces it with '' (nothing). You end up with ... -I. -I -Isome/src/path -I/some/src/path/ ... then the -I -Isome/src/path is interpreted as a single '-I' with argument '-Isome/src/path'. To work around this, I make the following the adjustment (hack) to INCLUDES: INCLUDES = -I. -I$(@D) -I$(@D) -I$(srcdir) -I$(srcdir)/$(@D) \ -I$(srcdir)/...

Hello, hope you can help me. I want to encode a video, which I have exported from Keynote (a program for presentation like MS Power Point) using ffmpeg2theora for html5 web delivery. The result only plays very buggy - frames are dropped, the video hangs and vlc can not output the correct length of the ogv video. Here is the source and the result for download, if you want to reproduce it: the

Estimada comunidad, tengo un problema que no puedo resolver. Tengo muchos archivos (los llamaremos "TMP") con los que debo construir un archivo resumen que llamare "DAT". A partir de los nombres de los archivos TMP construyo las primeras 4 columnas de DAT, luego, con datos del interior del archivo TMP construyo las columnas 5 a 9 de DAT. El problema insoluble que tengo es que

When reading the documentation for the "sleep" data set in R, the impression is clear, this is an "independent groups" kind of design (two groups of 10 subjects each). However, when browsing the original article (referred to in the help file), my impression is quite clear, this is really a "repeated measures" kind of data (one group of 10 subjects, two

Hi I have found that utorrent doesn't display its systray icon unless I switch from dual screen to single screen. When I login to twinview the systray icon is missing but if I use nvidia-settings I can switch to a single screen. and back and have a systray icon. However if I restart utorrent it will be as before and no systray icon. Should I file a bug report here(bugzilla) or with

Hola, En vez de utilizar "&" (que es "and") utiliza "|" (que es el "or"): graph <- graph[graph$sol=="lim" *|* graph$dia==2,] Saludos, Carlos Ortega www.qualityexcellence.es El 12 de julio de 2013 23:22, Freddy Omar López Quintero < freddy.vate01@gmail.com> escribió: > Hola de nuevo.

Dear List, With regard to the question I previously raised, here is the result I obtained right now, brglm() does help, but there are two situations: 1) Classifiers with extremely high AIC (over 200), no perfect separation, coefficients converge. in this case, using brglm() does help! It stabilize the AIC, and the classification power is better. Code and output: (need to install package:

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.
