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 have built a sequence of eight S4 classes, each of which inherits from the previous one but adds extra slots. I have a corresponding generic function for which I have described methods for each of these classes in a signature with one other variable. There are also some ad hoc variable outside the signature which have different default values for each class. Each method calls

Hi all (especially R-core) I suppose, With the introduction of the new functional programming functions into base I thought I'd ask for a Curry() function. I use a simple one that looks this: Curry = function(FUN,...) { .orig = list(...);function(...) do.call(FUN,c(.orig,list(...))) } This comes in really handy when using say, heatmap():

Some quick questions about S4 methods. Does the typing of S4 methods mean that lazy evaluation is no longer possible? It seems that you would need to evaluate the arguments to determine their type at dispatch. Second, what role, if any, do default arguments play in S4 methods? I notice that you can put default arguments into generics but that the dispatch is still done on the type of the

For the last, I dunno, week or so I've been unable to build R... I finally took the time to investigate and the crash is in building 'methods': all.R is unchanged ../../../library/methods/man/methods.Rd is unchanged make[2]: `Makedeps' is up to date. ../../../../library/methods/libs/methods.so is unchanged make[1]: Nothing to be done for `Rfiles'. Any clues to where this

Here is an example: setGeneric("foo", function(x, y) standardGeneric("foo")) setMethod("foo", c("numeric", "ANY"), function(x, y) cat("I'm the foo#numeric#ANY method\n") ) Dispatch works as expected but selectMethod() fails to find the method: > foo(1, TRUE) I'm the foo#numeric#ANY method >

I have classes A and B, where B contains A. In the implementation of the group generic for B I would like to use the corresponding group generic for A. Is there a way to do that? I would also appreciate any comments if what I'm trying to do seems like the wrong approach. Here's a stripped down example: setClass("A",

Hi, I have some questions about ssh server and Linux, hope someone can help me :) 1. Does Ssh server have a limit for the number of users that can connect ? 2. Does Ssh have restrictions about an username length? Or username format? We would like to use something like: foo_<GUID> ex: foo_ 5CEB80CF-150F-4ff0-8743-A6493FA200C1 3.

Hi Michael, Thanks for looking into this. I suspect that truncation of ANY suffixes from method signatures is also the culprit behind the sudden breakage of aliases of the form \alias{foo,numeric-method} when a method without the ANY suffix in its signature gets added to the ecosystem. See my post about this to the Bioc-devel mailing list a couple of months ago:

Fine with me as long as eliminating the inconveniences associated with it can be put on the roadmap. The alias instability and the fact that the user has no way to know if s/he should do ?`foo,numeric-method` or ?`foo,numeric,ANY-method` to find the method has been a long-standing problem. H.

Hi all, I'm having a problem with some sort of interaction with try() and methods, I think. The setup is as follows, I have an S4 class that holds an environment and I would like to evaluate the right hand side of a function inside that environment. No problem there. However, if the formula involves a symbol that doesn't exist, which may or may not happen, it fails as it should and

Is the anonymous CVS repository for R presently broken? There haven't been many updates coming through and the repository files seem to differ significantly from the rsync version of R-devel...

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
