Hello R-Team, May you help me to post a 'S4-creating Package Problem'? Thanks already now for supporting. The problem sounds like: Hello R forum, while compiling my R-package these 'Warnings' occur: ... Warnung in matchSignature(signature, fdef, where) : in the method signature for function "plot" no definition for class: "prediction" Warnung in

Hello to the list Some days ago, I placed a question on this maling-list and received an answer from Martin that I tried to follow. Unfortunately, I am still puzzled by the next step. I spent the whole Week-end in gathering information from the net. Some of them are almost contridtcory and I lack a good document to help me. So my first question would beL Is there a convenient document which

Hello, I would like to build shared lib for R using cygwin environment. After installing needed tools (mainly perl, make and compilers), I ran R CMD SHLIB hw.c But I get the following error : $ R CMD SHLIB hw.c c:/PROGRA~1/R/R-26~1.2/src/gnuwin32/MakeDll:82: *** multiple target patterns. Stop. Google it didn't give me any hints. Thanks for your help. Sylvain Archenault.

We are building a package, and want to create S4 methods for both head and mean for our own BigMatrix class. Following the recommendation in "Writing R Extensions" we use exportMethods instead of export in NAMESPACE (this is described as being "clearer"). This works for head, but not for mean. Obviously we importFrom(utils, head), but don't need to do this for mean,

In > R.version.string [1] "R Under development (unstable) (2011-12-15 r57901)" section 1.6.6 of 'Writing R Extensions' says Note that exporting methods on a generic in the namespace will also export the generic, and exporting a generic in the namespace will also export its methods. and Note that importMethodsFrom will also import any generics defined in

Dear List: Sorry for posting maybe a trivial question, but I have a basic understanding problem. If I have say pack1 and pack2, two R packages, and pack2 depends on and imports pack1 fully (as in the code below), is there a way to make all the functionality of pack1 available for the global and other environments (not only for the functions called from withing pack2) by loading pack2 only? I

I have encountered an issue which I have been unable to resolve, involving an S3 generic (print) being declared S4 generic in a package, and the method being exported. This all works fine - the problem occurs when I try to import the method to another package. Here is the bit that works fine. ------------- #the .r file for package bar

Dear List, consider the following scenario: setClass(Class = "A", representation = representation(B = "B", C = "C")) setClass(Class = "B", representation = representation(C = "C")) setClass(Class = "C", representation = representation(something = "character")) Obviously, the collation for sourcing these defs needs to be: C,

Dear list, It seems that a package (pkgB) using another package (pkgA) with S4 generics formed by taking existing functions (for example 'plot') must not import the existing functions ('plot') in its namespace to avoid the warning "replacing previous import: plot". Suppose we use the simple 'import' directive in the name space of pkgB. pkgA and pkgB files would

Hello everyone. R-2.12.0, suse linux 11.3. I am debugging a package that uses S4 methods and R CMD check gives the following warning: > Warning in methods::findMethods(g, env) : > non-generic function 'mdm' given to findMethods() > See the information on DESCRIPTION files in the chapter 'Creating R > packages' of the 'Writing R Extensions' manual. I

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

Hello, I'm trying to package some source files that link R to a broker using a Java API and the rJava package. I am successful doing the connection and operate on it using my R code. I would like to package the files and release the package. I created some S4 classes to hold several Java objects. I use WinXP and R 2.7.1. I've searched RSeek and the Wiki for help, but could not find a

Hi the list, Using S4, how can we create a package? In "S4 Classes in 15 pages, more or less", they put all the classes definition in a function that will be called at the opening of the library and they add "by hand" a Rd file. Is it the only way ? Is there something like "S4.package.skeleton"? Thanks Christophe

PkgA wishes to write a method for 'unique' on S4 class 'A'. ?Methods indicates that one should setGeneric("unique") setClass("A") unique.A <- function(x, incomparables=FALSE, ...) {} setMethod(unique, "A", unique.A) Both S3 and S4 methods need to be exported in the NAMESPACE import(methods) S3method(unique, A)

Late to the show on this release, unfortunately. One of our production packages no longer builds under R-2.15.0 with the following message. ** testing if installed package can be loaded Error: Function found when exporting methods from the namespace 'SuperCurve' which is not S4 generic: 'image' Possibly relevant clues follow: ## From R/AllGenerics.R if

Dear all, It is my understanding that using 'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj'

Hello, I wrote a package, which in the NAMESPACE file exports functions like this: exportPattern("^\\rh") On R-2.8 (Linux, 64), upon loading the package I have the rh functions present. On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not loaded, i.e the only function is rhyper (which is not from my package). Is there something wrong with my package setup?

pkgA's NAMESPACE has importFrom(graphics, plot) exportClasses("A") exportMethods("plot") R/foo.R has setClass("A") setMethod("plot", "A", function(x, y, ...) {}) During R CMD INSTALL pkgA_1.0.tar.gz we are told ** preparing package for lazy loading Creating a generic function for 'plot' from package

Dear all, I am experiencing some problems with S4 method overloading. I have defined a generic for graphics:plot, using setGeneric("plot", useAsDefault = plot) and with importFrom('graphics', 'plot') and exportMethods('plot') in the NAMESPACE file of pkg A. I then proceed to define a method for signature c('myS4class', 'missing'). This works

I've installed R-devel R Under development (unstable) (2014-07-09 r66111) Platform: x86_64-apple-darwin13.1.0 (64-bit) and am trying to resolve some problems that I am seeing with my SparseM package. In prior versions I explicitly had: setGeneric("image", function(x, ...) standardGeneric("image")) and then used setMethod to define a method for the class matrix.csr but
