similar to: (PR#13209) Arith ops dropping S4 *and* 'object' bit [Was: ...]

The asymmetry is just the symptom of a more fundamental issue: There are no operator methods currently defined for "vector" classes, either combined with each other or with a non-S4 object. The consequence is that computations drop through to the primitive C code. Not a good idea, because that code does various things to objects with attributes, some of them bizarre and most of them

Dear UseRs, Does anyone know when exactly the validity is checked in S4? Documentation is silent:(. Here is a small example: setClass("test1",representation(a="numeric")) setMethod("initialize","test1", function(.Object,...){ a<-runif(1) ## here slot "a" is initialized ## callNextMethod(.Object,a=a,...)

Hi, I have two example packages, test1 and test2, where the only code in them is: setGeneric("predict", function(object, ...) standardGeneric("predict")) (get them from http://www.cs.mu.oz.au/~gabraham/test1.tar and http://www.cs.mu.oz.au/~gabraham/test2.tar) The difference between them is that first does not have a namespace, and loads fine. The second has a namespace

Can someone explain what the problem is when I use the generating function? And how to get debug() to stop in the Superclass initialize method? ---- source ----- setClass("Superclass", representation(id = "character"), contains = "VIRTUAL") setMethod("initialize", signature(.Object = "Superclass"),

Hi, Say I have two packages, test1 and test2, that both define the generic method train (identical definition), and each has a specific train method for a different S4 object (foo and bar, resp.) I want to be able to call train(foo, x, y) and train(bar, x, y), which doesn't work since test2 masks test1, as seen below. The two solutions I can think of are to a) prefix train,

One of the changes some packages are noticing from the recent modifications to methods is warnings of "undefined classes" during installation when the package extends S3 classes or uses them as slots UNLESSS they have been declared in a setOldClass() call. The green book "strongly recommends" declaring S3 classs this way (pp 449-451). The warnings on undeclared classes

Dear R, I have two R instances running at the same time, say instance A and instance B. Is there a simpler way to pass the data in A to B? More precise, I have a stupid example: In instance A, I am running a function "test1" test1 <- function (x1) { x2 <- sin(x1) return(x2) } In instance B, another function "test2" test2 <- function (x2) { x3 <-

Some changes to the implementation of S4 classes in the methods package will be committed to the r-devel version, probably later today. They should be largely back-compatible (exception noted below) but they are fairly extensive, so this is an advance notice. The changes form the first of a two-stage change aimed at making the implementation more consistent with R semantics, in particular with

Hello, I have a question concerning "setClassUnion". I'm working with R 2.0.0 Patched (2004-10-06) on windows 2000. I tried to use "setClassUnion" in a package I am currently working on. The situation is similar to the following example: The DESCRIPTION file has entries: Depends: R (>= 2.0.0), methods Imports: methods LazyLoad: yes The NAMESPACE file has

Hi, But "any" rises some other problems well known from S3. One has "any" for "free" in S3. You don't need S4. . But I know how "if" polluted functions look like in S3. They are hard to understand and to maintain. Hence I am quite happy to use S4. Type-checking is usefull if you program with data. Also if you are on the "C side" of the

Hello everyone, I've come up with a problem with using paste() inside apply() that I can't seem to solve. Briefly, if I'm using paste to collapse the rows of a data frame, AND the data frame contains strings with spaces, AND there are NA values in subsequent columns, then paste() introduces spaces. This only happens with that particular combination of data values and commands. I have

The current version of the methods package now has a namespace. Packages using S4 methods and classes can have NAMESPACE files. New directives can be included in NAMESPACE files to import and export classes and methods. Namespaces allow cleaner definition of the API for packages, and are needed for future improvements to R. NOTE: This is a major revision. In principle, it should be back

Would we really need the special class or would simply checking the formals of the method against those of the generic be simple and fast enough?

Dear all I am looking for a solution for a module to define alle possible user and then install the one or more user from that module if needed on a server, but not all of them. My idea is something like this. Can I define a user in the nodes.pp at a special Server to install that user? init.pp class admin_user::group { group { "group1": gid => "888",

Hello all, after recent upgrade from 2.0.5 to 2.0.8 it seems that local seen flags for mails reside in shared mailboxes doesn?t work anymore. Before the upgrade I had read mails with account #1. Account #2 (who has access via acl) saw the mails still as unread. Now, no matter who read the mails, the other account see the same flags, immediately. I read the related wiki pages again and tried to

Hi, Background : I am using rsync to push/sync FTP uploaded files from master server to slave servers. On slaves the full directory path of each file doesn't exist so rsync is unable to sync it and there a no options in rsync to do something like "mkdir -p/install -D -d" on destination before sync file. N.B. I don't want to do a full sync of the root/home directory every time a
