Dear List, I’m doing my first baby steps towards developing own R Packages and ran into the following problem: R CMD check mypackage works fine (no errors, no warnings) R CMD build mypackage works fine (no errors, no warnings) R CMD INSTALL –library=”C:\R\R-2.11.1\library” “something\mypackage\mypackage_1.0.tar.gz” works fine (no errors, no warnings) However, when I try loading the

Dear list, I was wondering if you could help me out in clarifying something: Is it possible to use class "ANY" in slots/fields of formal classes if you a) do not want to restrict valid classes of that field and b) if you are making explicit use of class inheritance? It seems to work in simple scenarios but produces errors when class inheritance comes into play. So I was

Dear list, just to make sure that I understand 'unregistering' methods for S4 reference classes correctly: If I registered a method and want to 'unregister' (i.e. remove) this method again, objects/instance created of the respective class still feature the removed method until I do an explicit reassign ('my.instance <- getRefClass("Classname")$new()'), right?

Dear list, somehow I can't get the Roxygen tag "@example" to work for me. My "Roxygen-Header" of a script containing, say, a function looks like this: #' My header #' #' My description #' #' @param a Blabla. #' @param b Blabla. #' @return \code{TRUE}. #' @callGraphPrimitives #' @references #'

Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and

Hi there, is there a way to create a NAMESPACE file based on Rd-files (or whatever is needed in order to apply the regular expression "^[[:alpha:]]+" without(!) resorting to package.skeleton() (as this kind of interferes with roxygenize() pretty often)? Thanks a lot, Janko [[alternative HTML version deleted]]

Dear List, I am not really familiar with any other language than R, but I?ve heard that in other languages there is something called ?self referencing?. Here?s what I?m trying to get an answer for: Suppose there is a function that takes as its input a value of a slot of an S4 object. The function itself is stored in another slot of the SAME S4 object. Is it then possible to have the function

Dear List, I'd like to set up a package repository so I can use install.packages() on it for home-grown packages. I set up an AMPP infrastructure on a windows box already, but I'm pretty lost with respect to what to do next as I didn't do any web-programming/admin yet. Could anyone recommend some r-specific tutorials or has a couple of suggestions for me? I've had a look at the

Sorry, I listed the wrong package in the header of my previous post! >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Dear List, has anyone of you experienced a significant increase in the time it takes to parse an URL via "htmlTreeParse()" when this function is called

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,

Hi Gabriel, and thanks for answering. I'm basically just trying to find a way to use the power of `...` in more complex scenarios and I'm well aware that this might not be the best approach ;-) Regarding your actual question: "Are you suggesting methods be dispatched based on the *contents* of ... [...]?" Yes, I guess currently I kind of do - but not on the argument *names*

Well, the benefit lies in the ability to pass along arguments via `...` to more than one recipient that use *identical argument names* and/or when these recipients are not necessarily located on the same calling stack layer. I'm *not* after a *general* change in the way arguments are dispatched/functions are called as I'm actually a big friend of keepings things quite explicit (thus

Dear list, a while ago I posted this at r-devel but got no answers. Hope it?s okay to give it a shot again by cross-posting it here.

Dear list, today I stumbled across the function ?nsl()? for the first time in order to perform a hostname lookup. According to the R Reference Index (Version 2.9.1, page 1522), the function should be part of the "utils" package. However, I cannot find it in the utils package of my installation(s). I've tried the R-versions 2.8.1, 2.9.0 and 2.9.1. I'd be very thankful if

Dear list, I hope this is the right place to post a feature request. If there's exists a more formal channel (e.g. as for bug reports), I'd appreciate a pointer. I work a lot with named nested lists with arbitrary degrees of "nestedness". In order to retrieve the names and/or values of "bottom layer/bottom tier", I love the functionality of 'unlist()', or

Thanks a lot for answering. Before I get into it, please note that everything below bears the big capture "Thanks for trying to help me at all". 1) Yeah, those examples - quite hard to satisfy everyone's needs ;-) While the one side complained that my past examples regarding this issue were not informative enough, others didn't like the more elaborated version (as seems to be

Dear list, I came across a behavior that IMHO is somewhat undesired when calling '$field()': If the field name whose value you're trying to get is *not* a valid field of the Reference Class, then R doesn't stop there with an error, but scans through all enclosing environments/frames. The result is something similar to calling '|get(<objname>, inherits=TRUE)|'
