similar to: setMethod sometimes fails to set package slot when signature has trailing 'ANY'

Hello, I have a simple class that looks like: setClass("statisticInfo", representation( max = "numeric", min = "numeric", beg = "numeric", current = "numeric", avg = "numeric", obs = "vector"

Interrogating some (of my own) code in another package. >norm.meth <- getMethod("normalize", "MatrixLike") >message("str(norm.meth)") >str(norm.meth) >message("show(norm.meth at .Data)") >show(norm.meth at .Data) Last show() displays this: function (object, ...) { .local <- function (object, method = c("median",

I'm attempting to reflect the information for use with corresponding fields in GUI (in a different package), to provide default values, argname as key for UI label lookups, etc. So I want something much more like the formals of the implementation: { "object", "method": c("median", "vs", "tukey"),

Hi, Strange things happen. Here is a simple example: > setClass("A", contains="integer") > setMethod("as.matrix", "A", function(x, ...) t(callNextMethod())) Creating a generic function for ?as.matrix? from package ?base? in the global environment [1] "as.matrix" > a <- new("A", 1:3) > as.matrix(a)

I wish to make modifications to the plot.pedigree function in the kinship package. My attempts to contact the maintainer have been unsuccessful, but my question is general, so specifics of the kinship package might not be an issue. My first attempt was to make a new function Plot.pedigree in the .GlobalEnv which mostly achieved what I wanted to. However, I'm sure that's not the tidiest

Agreed, definitely. The current hack is to avoid re-matching arguments on method dispatch, so a fix would need to be fairly deep in the

Hi, perhaps a little bit unusual: is it possible to use "<- " as generic function with a new signature? The following example doesn't work: > isGeneric("<-") [1] FALSE > setClass("A",representation(x = "numeric")) [1] "A" > setClass("B",representation(x = "numeric")) [1] "B" > myAssign.A <-

hello, if i load the RSQLite package in addition to the RPostgreSQL package, i get various errors when trying to use RPostgreSQL functions. here is an example transcript showing one such error: ========================================================== R version 2.15.0 (2012-03-30) [...] > packageVersion('RPostgreSQL') [1] 0.3.2 > packageVersion('RSQLite') [1] 0.11.1

Hi R-helper! I have problem with setMethods for "[". Here is example : setClass("myClass", representation(ID.r = "numeric", ID.c = "character", DAT = "matrix")) to.myClass <- function(ID.r, ID.c, DAT) {     out <- new("myClass", ID.r = ID.r, ID.c = ID.c, DAT = DAT)     return(out)       }       setMethod("[",

For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

Hi r-devels, I am stuck in some S4 inheritance problem: setClass("A",representation(a="numeric")) setClass("A1",representation(b="numeric"),contains="A") setClass("A2",representation(c="numeric"),contains="A1") if(!isGeneric("foo")){ setGeneric("foo", function(x,y,z, ...)

Hi, we have some questions concerning the definition of new arithmetic methods. In our package "distr" (on CRAN) we define some new arithmetic methods for "+", "-", "*", "/". After loading "distr" the corresponding arithmetic methods work. Now, if we define a new class and also a new method for one of the arithmetic methods

Would you please clarify your exact use case?

In my package, I create a new method for plot with the following signature: setMethod("plot", signature(x="marrayNorm", y="formula"), plot.ma) where marrayNorm is a class defined in the marray package. After building and installing my package, I get the following warnings when I load my package (with library(maVis)): Warning messages: 1: In the method signature

At this point I would just due: formals(body(method)[[2L]]) At some point we need to figure out what to do with this .local() confusion.

Hi, We've observed rather strange behavior related to as(). When as() is used to make a conversion to a super class, an invalid entry is inserted into the table of methods. > setClass("A", contains="list") > get(".MTable", environment(coerce))[["list#A"]] NULL > as(list(), "A") > get(".MTable",
