similar to: S4-based package failure: setGeneric example#1

I am a newbie package builder who successfully built a "Hello world" package but am now having trouble building a package with S4 functionality. I thought I would start by building a package consisting of just the first example under the setGeneric help page in a "fresh" 2.10.0 (windows) console (methods loaded at startup). The example: ## create a new generic function, with a

Hi the devel list. I am adapting the package.skeleton to S4 classes and methods I would have been very proud to post a new working function on this list. Unfortunately, I do not manage to solve all the problems. Mainly - sys.source does not compile a file with setClass - dumpMethod does not exists yet In the following code, thise two problems are notified by a line ################# Still

r-devel, In a development version of the CRAN package metrumrg, I write ... require(reshape) setGeneric('cast') setOldClass(c('keyed','data.frame')) setMethod('cast','keyed', function ...) The result is satisfactory when sourcing the code directly, but when checking the package (which has 'reshape' as a dependency in the DESCRIPTION file) I get

R-helpers: I'm trying to build a package, but I'm a bit new to the whole S3/S4 methods concept. I'm trying to add a new definition of the zoo function "as.yearmon", but I'm getting the following error when it gets to this point during a package install: *** R CMD INSTALL STARStools * installing to library

Hey everybody, I'm VERY new at using Wine, so forgive me if this is a foolish question! Recently I've been trying to run the Torchlight 2 Beta under Wine? the game itself runs flawlessly, but in order to get it to run past the beta expiration date I have to run another application (I'm not entirely sure what it is, my belief is that it emulates a server of some sort to play on). No

I created some S4 objects that are essentially data frame objects. The S4 object definitions were necessary to verify data integrity and force a standardized data format. I am, however, finding myself redefining all the typical generic functions so that I can still manipulate my S4 objects as if they were data frames ... I have used setMethod to set methods for "subset",

1. Is it always the case that when defining generic functions in a package, the package needs to be installed as a binary package to avoid having the generic functions in the .GlobalEnv? 2. Defining a generic function in a "non-binary" package triggers a check warning $ R CMD check ... ... * checking for code/documentation mismatches ... WARNING Objects

Full_Name: Ross Boylan Version: 2.10.0 OS: Windows XP Submission from: (NULL) (198.144.201.14) Some of the help for setGeneric seems to have been garbled. In the section "Basic Use", 5th paragraph (where the example counts as a single line 3rd paragraph) it says <quote> Note that calling 'setGeneric()' in this form is not strictly necessary before calling

Is it safe to call setGeneric twice, assuming some setMethod's for the target function occur in between? By "safe" I mean that all the setMethod's remain in effect, and the 2nd call is, effectively, a no-op. ?setGeneric says nothing explicit about this behavior that I can see. It does say that if there is an existing implicity generic function it will be (re?)used. I also tried

In the last few days I've received couple of messages pointing out that our SparseM package fails to install on the patched version of 1.7.0. Laurent Gaultier kindly suggested that replacing: setGeneric("as.matrix.csr") by setGeneric("as.matrix.csr", function(x, nrow, ncol, eps) standardGeneric("as.matrix.csr")) was sufficient to fix the problem.

This is a correction to my previous message, I forgot to swap two lines in the body of setMakeGenericMethod. Sorry about that. The correct (full message) reads like this: Hi, This works > setGeneric("clear", function(obj) standardGeneric("clear")) [1] "clear" but this doesn't. Why? > funName <- "clear" > setGeneric(funName,

Are there any assumptions I can make about the order in which different files in the R package subdirectory will be evaluated? For example, will it be alphabetical in the file names? Will case distinctions be ignored? I ask because I would like to use setGeneric, as in setGeneric("foo", function(x) standardGeneric("foo")) and am wondering where that should go. I realize I

Hello, If the signature of a method defines which generic it implements then I'm confused about why this minimal example I invented won't work : setGeneric("myFun", function(rs, ...){standardGeneric("myFun")}) setGeneric("myFun", function(cs, ...){standardGeneric("myFun")}) setMethod("myFun", "numeric", function(rs, colour =

Dear all, I can't see how setGeneric() works. I know perfectly well how to define library(methods); setClass("Square", representation(side="numeric")); # Will become the default method. getArea <- function(object) { stop(paste("Method getArea() is not defined for this class:", data.class(object))); } setMethod("getArea",

Hi the list When two setGeneric occurs on the same function, the second erage the first and erase all the function previously define. Is it possible to prevent that ? Is it possible to declare a setGeneric that can not be erased later ? Something like the |sealed for setMethod...| || |Thanks| || Christophe

The problem is not specific to redefining the q function, but to the interaction of assignInNamespace and setGeneric. The latter requires, roughtly, that the environment of the function being replaced by an S4 generic is (or is the descendent of) the environment in which it lives. E.g., the following demonstrates the problem % R --quiet --vanilla > assignInNamespace("plot",

Hi list, Calling setGeneric()/setMethod() from within the .onLoad() hook of MyPkg package produces the following error: > gctorture(TRUE) > library(MyPkg) .onLoad(): ok1 .onLoad(): ok2 Error : protect(): protection stack overflow Error : .onLoad failed in 'loadNamespace' for 'MyPkg' Error: package/namespace load failed for 'MyPkg' This is with

Hi Bill, Ideally, your coworker would just make an alias (or shortcut or whatever) for R that passed --no-save to R. I'll try to look into this though.

Hi, while playing with the `methods' package I was not able to find what the recommended way of dealing with the following problem is. Suppose there is a generic function `foo' and two functions `foo.default' and `foo.formula', in the classical way: foo <- function(y, ...) UseMethod("foo") foo.default <- function(y, ...) {} foo.formula <- function(formula,

Hi R version 2.4.0 alpha (2006-09-06 r39158) MacOSX 10.4.7 There was a thread some time ago as to whether the structure created by package.skeleton() would pass R CMD check. I have an example where package.skeleton() gives an R file that gives an error when sourced. If I type setClass("brob", representation = representation
