I have Windows XP build scripts that look for R in a variety of folders and if multiple ones are found, takes the last one. For example, I currently have the following in \Program Files\R : rw1060 rw1062 rw1071 rw1071beta rw1081 rw1090 rw1090dev rw1091 rw1091pat rw2000 rw2001beta Note that it currently correctly gets rw2001beta but if I add rw2001 then it will not pick it up since

hi I need 'rw1062.zip' since i can't get excel, R1070 or R1071 to work with the R (D)COM Server everything worked fine in the god rw1062 days the lapack routines can't be loaded 'unable to load shared library c:\r/moduleslapack.dll, the specified library could not be found' don't know if it's the forward slashes that anoys windows btw, the libraries are in the

I've recently done a lot of re-writing of the internals of RODBC, and have a test version 0.99-6 available. This is a run-up to the release of 1.0. Both the source code and a Windows binary (prepared under rw1062) are available at http:/www.stats.ox.ac.uk/pub/R, and I would appreciate some real users testing this version. It should be more efficient as data frames are transferred to and from

Va ejemplo: data <- Ejemplo_List cl<-round(seq(0,max(data$h),10),2) # seq para clases df<-data.frame(min.h=cl[-length(cl)],max.h=cl[-1]) # Data frame con las clases df$class<-paste(df$min.h,df$max.h,sep="-") # Armo las Clases df$Largo <-NA # Variable nueva # Completo la columna "Largo" con la cantidad de observaciones que están entre el mínimo y el máximo de

La verdad es que todas las aportaciones son muy muy interesantes, MI pregunta siguiente: Habeis usado R para programar orientado a objetos alguna vez? Porque yo hago mucho scripting.... Supongo que por mi mala calidad como programador...

Hello fellows: I've een trying to set up a function that performs 100 loops producing the coresponding 100 series. I want to save all those datasets in a dataframe, so I wrote this... prep <- function() # Clase[1]/Categoria[2]/Phi[3]/Rf[4] peso <- c(.0,.03,.3,.6) # Extension del calculo for (i in 1:100) { # Calculos de todas las curvas # Variables (Valor Base) abase

See ?rpart.control.

Hi R users, I have been trying to install and use RMySQL on Windows98 for MySQL3.23.55-max using the pulldown menu. I am getting the following errors. I read the doc and some archived mails about a similar problem on unix like systems. Still can't get it to work. Some info below that may indicated where the problem is: * The directory RMySQL\libs is empty---I was not expecting this. *

Not really an R question but I'm hoping someone can help me out. I'm having problems with the R help page "The R language" and Mozilla 1.3 with the Java 2 runtime environment 1.4.1_02 under Windows XP. The problems occur on the "Search Engine & Keywords" page. I can open two links, but after that links aren't recognized. The problem seems to be javascript

Buenas mi duda es cómo sumar los valores de una variable dentro de una clase ya creada. Por ejemplo: #Creo el dataset que voy a completar, primero la secuencia con la q hare las clases: cl<-round(seq(0,max(data$h),0.5),2) # Mi data frame con las clases df<-data.frame(min.h=cl[-length(cl)],max.h=cl[-1]) # Creo la columna "Largo" con la cantidad de observaciones que están entre el

Hello all, this is the first time I'm using R and e1071 package and SVM multiclass (and I'm not a statistician)! I'm very confused, then. The goal is: I have a sentence with sunny; it will be classified as "yes" sentence; I have a sentence with cloud, it will be classified as "maybe"; I have a sentence with rainy il will be classified as "no".

Hola, He seguido con interés el mensaje de Carlos sobre la guía de estilo para programar en R aparecida en Google y las reacciones que ha generado. En líneas generales creo que la guía Google es bastante floja, estoy de acuerdo con la mayoría de comentarios iniciales de Carlos y en particular con el hecho de que no trata en absoluto (ni lógicamente promueve) la creación de packages.
