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

described in the package's vignette,

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

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

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

Possible bug in class 'POSIXlt' when including microseconds?
Dear list,
I'm a bit puzzled by an ambiguity with respect to the representation of
micro-/milliseconds when using 'POSIXlt' objects.
It seems that the last digit of the 'sec' attribute sometimes seems to
differ from the digits shown when printing the 'POSIXlt' object. You'll
find a little SO post with some example code here:

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*

Is it possible to define a function's arguments via a wildcard in 'substitute()'?
Dear List,
just out of pure curiosity: is it possible to define a function via
'substitute()' such that the function's formal arguments are specified
by a "wildcard" that is substituted when the expression is evaluated?
Simple example:
x.args <- formals("data.frame")
x.body <- expression(
out <- myArg + 100,
return(out)
)
expr <-

Significant memory leak when using XML on Windows

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

S4 Reference Classes: undesired behavior when calling method '$field()'
Dear list,
I came across a behavior that IMHO is somewhat undesired when calling
'$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)|'

Bug: argument 'lib.loc' not passed on appropriately in 'library()'?
Dear list,
I'm experimenting with setting up custom 'lib' and 'destdir' directories
for my R packages. It seems to me that 'library()' does handle a custom
'lib.loc' argument the way it should for an arbitrary package but NOT
for its dependencies on other packages. The latter are looked for in the
default lib path (~/R/R-2.x.x/library) and NOT in the custom

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

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:

Query super- and subclasses of a class: is there a better way than to use 'completeClassDefinition()'
Dear List,
when I first started to use S4 classes, I used the function
'completeClassDef()' in order to see the super- and subclasses of a
certain class:
setClass(Class="A", representation=list(a="numeric"))
setClass(Class="B", contains="A", representation=list(b="character"))
# Super
