Estimados compañeros me gustaría saber si alguno ha utilizado la función add_model del paquete modeval cuando la variable de clasificación (y) tiene más de dos niveles. Porque si la utilizo con más niveles siempre me sale el error: Error: length(levels(factor((purrr::as_vector(y))))) == 2 is not TRUE Me parece muy interesante el paquete y no veo donde indica esta limitación. Un cordial

Hi, I'm not sure if this question has been answered before, but when I execute command "Rcmd INSTALL --build nws" to build an R package on Windows, the build process got stucked on the save image step. Here is the snapshot of the build process, --- Making package nws ---- adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files

R-exts says Both install.R and R_PROFILE.R should be viewed as experimental; the mechanism to execute code before attaching or installing the package may change in the near future. With the other facilities available as from R 2.0.0 they should be removed if possible. Every usage of these on CRAN is unnecessary. If you want to save the image, say so in the SaveImage field in

No Carlos la limitación está en la función add_model porque si utilizo randonForest fuera de esa función no existe limitación en el número de categorías de la variable de clasificación. He escrito al autor de modeval y espero también su respuesta. Además he probado a dejar el modelo con dos categorías y la función no da error. Un cordial saludo, Juan El 08/06/2017 a las 13:39, Carlos

I'm trying to sort out some best practices for package development and understand some behavior of R CMD check that has me confused. Best practice question: If a package foo appears in the Depends field in the DESCRIPTION file of mypkg, should I refrain from using require(foo) in the R source files of mypkg? The Writing R Extensions manual says this about the Depends field: ... the

According to R-exts: The second purpose for @file{install.R} is to hold code that needs to be executed each time the package is attached, after the image is loaded. Few packages have a need for such code so @file{install.R} is normally an empty file. The optional file @file{R_PROFILE.R} is executed before the code in the @file{R} subdirectory and should be used to set up an

Hi I Can't connect to the Oracle database, any tips? Has anybody actually got ROracle up and running on windows? >> unable to find an inherited method for function "dbConnect", for signature "OraDriver" I can happily connect to the same database through RODBC.

Hello, I have some troubles when building S4-class packages. All my (S4-)code works well (without building a package). When building a package, in the R prompt after checking S3 generic/method consistency Following error occurs: Fehler: Kann R Kode in Packet 'AddNoise' nicht laden (~Error: Can not load R code from package 'AddNoise') (and there are some warnings after the

Dear useRs, a new package for tree-structured regression is available on CRAN. This package implements a unified framework for recursive partitioning which embeds tree-structured regression models into a well defined theory of conditional inference procedures. Stopping criteria based on multiple test procedures are implemented. The methodology is applicable to all kinds of regression problems,

Ah yes. There they are right on page 4 of "Writing R Extensions". The "LazyLoad: yes" was sufficient to avoid the check errors, but I'll add the "Depends: methods" as well. For the manual-impaired like me, it _may_ be worth reiterating these two requirements in section 1.6.6 "Name spaces with formal classes and methods" - right where the .onLoad

Hello, I have a very minimal package "simplepkg" (DESCRIPTION, NAMESPACE, and R) with S4 classes/methods (defines a class "foo" and a show method for that class" - both the class and show method are exported). I can seemingly install the package, then load and use it: > sessionInfo() Version 2.3.1 (2006-06-01) sparc-sun-solaris2.10 attached base packages: [1]

Hi, I've been using Samba for a while, and I'm now running all network printing here from Samba. However, while printing itself works fine, my users can neither view the print queue, nor delete jobs from it, and this is beginning to get annoying. I'm using LPRng to do all the printing. All the clients are NT4 workstations. Here's some selected bits of /etc/smb.conf and

Dear listers, I am making a trial to move from S3 to S4... I have created some classes of interest and they work acceptably well for the purpose. I am now wondering how to make them operate in a package. In clear when a package is loaded (eg library(mypackage)) where should I put the class descriptions:
