Hi,
According to its man page, callNextMethod() (called with
no argument) should call the next method "with the arguments
to the current method passed down to the next method".
But, for the "[[" and "[" generics (primitives), the argument
after the dots doesn't seem to be passed down:
setClass("
Hi,
When a method is not defined for an object, you
expect to get an error. But this is not the case for
"names<-". You can use "names<-" on any S4 object: it
will remain silent, giving you the impression that it
actually did something:
setClass("A", representation(vals="numeric"))
setMethod
Hi,
I can't get the non-abbreviated class names of the
rows and the cols of the Adjacency Matrix:
setClass("ClassWithALongName")
setClass("SubclassOfClassWithALongName",
contains="ClassWithALongName")
Trying all possible values for 'abbreviate' (with R-2.9.0):

In fact reg.finalizer() looks like a dangerous feature.
If the finalizer itself triggers (implicitely or
explicitely) garbage collection, then bad things happen.
In the following example, garbage collection is triggered
explicitely (using R-2.9.0):
setClass("B", representation(bb="environment

Sorry this is something I already reported one week
Hi lists,
Recently I needed to download a few R packages for Unix, Windows
and Mac OS X. The idea was to put them all together on a USB key
in order to be able to install them on systems without network connection.
It worked fine for the "src" and "win.binary" packages but I had the
following pr
Hi,
On Windows, 'install.packages(,type="source")' displays the same output
than 'R CMD INSTALL --help' and doesn't install anything...
This is with R version 2.4.0 alpha (2006-09-06 r39158).

Hi Duncan,
This is even more confusing with a matrix:
> x <- matrix(5:-6, 3)
> x

[2,]41 -2 -5
[3,]30 -3 -6
> x[invisible(2),3]
[1] -2
> x[2,invisible(3)]
> .Last.value
[1] -2

Hi,
Man page for 'convolve' says:
conj: logical; if 'TRUE', take the complex _conjugate_ before
back-transforming (default, and used for usual convolution).
The complex conjugate of 'x', of 'y', of both?
In fact it seems that it takes the complex conjugate of 'y' only which
is OK
Hi Martin,
Thanks for taking the time to read me. Here is a followup,
it's rather long but hopefully not too long (and not too boring) ;-)

Thanks! I will check SVN before reporting problems with a tarball.
Just hope that nobody will get too upset if I'm reporting a problem

Someone else might get something different. It all depends on the
values of its 'stringsAsFactors' option:

Hi,
?pairlist gives no explanation about what exactly is the difference
between a pairlist and a list (except that a pairlist of length 0
is 'NULL'). So, what's a pairlist?
