Require of gWidgetsRGtk2 fails: RGtk2.dll can't be found, but it's there
Dear list,
I've been trying to get gWidgets/gWidgetsRGtk2 to run every other month
for a while, but somehow I simply can't figure out what's going wrong.
I tried several distributions of the GTK runtime environment for Windows

Bug or feature: using "ANY" as a generic field class (was: '[R] Is there a (virtual) class that all R objects inherit from?)
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

Significant memory leak when using XML on Windows

Function "nsl()" missing in package utils
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

Significant memory leak when using XML on Windows
Dear list,
I'm sorry to keep coming back with this time and time again, but this bug
is still not fixed even though the root cause of the issue has been around
for 2-3 years now. And as the number of packages that depend on XML grows,
I thought maybe this deserves some wider attention.
I did my best to make reproduction of the issue as easy as possible:

Feature request: mixing `...` (three dots) with other formal arguments in S4 methods
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*

Stats not loaded? Method for as.ts() results in error
Dear list,
I've got the following problem:
In a package I'm trying to build, there exists a method for the function
"as.ts()". When checking the package, R always throws the error that it
cannot find a function called "as.ts". To me it seems that the package
"stats" (home of "as.ts()") is not loaded during the checking process even

Feature request: mixing `...` (three dots) with other formal arguments in S4 methods
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

Including data in packages
Dear List,
I would like to include a couple of objects in a package I am developing and
I don't really get it yet. The objects should be available after package
load as some functions depend on it.
I tried the following:
1) Bundling all objects that I need in the file '/R/sysdata.rda' as
described in the "Writing R Extensions" manual on page 7

Feature request: mixing `...` (three dots) with other formal arguments in S4 methods
Dear List,
I'm currently investigating if the argument dispatch mechanism based on
`...` could somehow be "generalized" to scenarios that involve `r`
recipients located across `c` calling stack layers *and* combined with the
S4 method mechanism (for those interested see

Roxygen: @example tag does not work for me

Reference classes: accessor functions via 'getRefClass(...)$accessors(...)'
Hi there,
I''d like to choose between an "static" and "dynamic" access of a reference
class field, say ''a''.
myObj <- getRefClass("Blabla")$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

Avoiding name clashes: opinion on best practice naming conventions
Dear List,
I'm trying to figure out some best practice way with respect to the naming
conventions when building own packages.
I'd like to minimize the risk of choosing function names that might
interfere with those of other packages (both available ones and those yet to
come).
I came up with following alternatives
1. Prefixing the actual names (e.g. myPkgfoo() instead of foo()): pretty

How to set up an own package repository
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

S4 Reference Classes: declaring public and private methods
Dear list,
is there a way to declare public and private methods in S4 Reference
Classes? If not, are there plans to add such a feature?
You'll find a small code example of what I mean at Stackoverflow:

reference classes: question on inheritance
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
