similar to: retrieve rows from frame assuming criterion

sorry for my previus (WRONG) answer, as someone already pointed out a solution could be subset(data, PUNTAR==c("IX49","IX48")) > -----Messaggio originale----- > Da: Guazzetti Stefano > Inviato: venerd?? 23 luglio 2004 15.55 > A: 'Luis Rideau Cruz'; r-help at stat.math.ethz.ch > Oggetto: R: [R] retrieve rows from frame assuming criterion > >

Still wrong: > x <- data.frame(a = sample(letters[1:3], 10, replace=T), b=1:10) > x a b 1 a 1 2 a 2 3 b 3 4 b 4 5 a 5 6 a 6 7 b 7 8 b 8 9 b 9 10 c 10 > subset(x, a == c("b", "c")) a b 3 b 3 7 b 7 9 b 9 10 c 10 > subset(x, a %in% c("b", "c")) a b 3 b 3 4 b 4 7 b 7 8 b 8 9 b 9 10 c 10 What matters

Yes, paraphrasing Murphy I can say of myself: "Nothing seems to be able to stop a stupid thought in its pathway from the brain to the keyboard". :-) Sorry once again and thank for your patience.

R-help, In the following loop : for(i in 1:8) { cc[[i]]<-tapply(test[,i+6],list(puntar=test$puntar),sum)/tapply(test[,5],list(puntar=test$puntar),sum) cbind.data.frame(cc[[1]],cc[[2]],cc[[3]],cc[[4]], cc[[5]],c[[6]],cc[[7]],cc[[8]]) } Is there anyway I can 'cbind.data.frame' the objects cc[[ i ]] without actually writing every single element?? In this case there are 8 but what if

R-help, I'm trying to do a simple box-and-whisker plot to some data. The data are a subset of a large data frame but when running the "boxplot" function on the subset data all the factors are still present in the graph leaving a huge empty space until the actuals factors are shown. This produces a spurious box-and-whisker plot. If the subset data are exported to another R session

Buenas a todos, La gente de DataCamp se han puesto en contacto con el grupo de Madrid para ofrecernos una oferta para usar gratuitamente su plataforma con diferentes cursos de R durante un mes. Les hemos preguntado si sería posible compartir este ofrecimiento con toda la lista de R-Help-es y no ven mayor problema, les ha parecido muy bien la posibilidad. El link de acceso es el siguiente:

Hola a todos, Tengo un problema con RStudio y la conexión a una base de datos. Desde la terminal no tengo problemas para ejecutar, por ejemplo: library(RODBC) channel <- odbcConnect("MiBaseDatos", uid = "MiUsuario", pwd = "MiContrasena") datos <- sqlQuery(channel,"SELECT TO_CHAR(S.B_STOD_DATO,'YYYY') \ , M.STODNR \ ... ... ...") pero desde

Carlos, al parecer tengo instalado el paquete RODBC en : /home/luisr/R/i686-pc-linux-gnu-library/3.0/RODBC/ no hay nada en (carpeta vacia): /usr/local/lib/R/site-library/ en el directorio: /usr/local/lib/R/site-library hay paquetes que vienen con R pero RODBC no saludos, Luis -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- Luis Ridao Cruz Faroe Marine Research Institute Nóatún 1,

No, no estoy usando Rstudio Server El 1 de abril de 2014, 9:07, Carlos J.

Hola, ¿qué tal? ¿Puedes comparar la salida del comando Sys.getenv("LD_LIBRARY_PATH") en una sesión en la que funciona RODBC y otra en la que obtienes el error anterior? Un saludo, Carlos J. Gil Bellosta http://www.datanalytics.com P.D.: A propósito, también he estado tratando de utilizar RODBC en Linux y me he acabado rindiendo. Sobre todo porque RJDBC funciona bastante bien.

Pues ahí lo tienes. De alguna manera R (a través de RStudio) no está incorporando el directorio /u01/app/luisr/product/11.1.0/client_1/lib donde se ve que tienes las librerías de ODBC al "LD path". Échale un vistazo a https://support.rstudio.com/hc/communities/public/questions/200641818-How-to-configure-libPaths-?locale=en-us Aparentemente RStudio tiene su propio sistema para

Hi Folks, I'm trying to install Debian onto a headless server (Supermicro X8SIE-LN4F motherboard). The on-board IPMI BMC redirects the serial port to COM3, and I can talk to it just fine over a remote console connection. I've been trying to install Debian remotely, and have the DHCP and TFTP servers working, and things seem to work (at least into the Splash screen) if I'm using

Hi, I've got some weird sound artifacts happening during calls, they're very hard to describe, so I have a 122kb recording: http://openprojects.rarcoa.com/~miztic/artifact.wav normally the artifacts are just short blips, not quite as long as the one above, but they sound the same. When using the aggressive echo suppressor, it seems like those artifacts cause a really loud buzzing sound to

I have written a few different summary functions. I want to calculate the statistics by groups and I am having trouble getting the output as a dataframe. I have attached one example with a small dataset that calculates summary stats and percentiles, I have others that calculate upper confidence limits etc. I would like the output to be converted to a dataframe with one of the columns as the
