Hadley sent me the package, and my guess *was* correct. The package is
not using lazy-loading, and early on it has (in aaa-top-level.r)
TopLevel <- proto(expr = {
...
That is 'a top-level computation'. To make this work, you need
require("proto") in that file. It also needs require("grid").

While I don't disagree with the general need to provide an interface
to SetDllDirectory, etc., I think the discussion about 3rd party
libraries has slightly missed the more obvious solution.
Instead of using a DLL, such packages can link against a _sta

Hi,
We will be holding an advanced course in R programming at the FHCRC
(Seattle), Feb 13-15. There will be some emphasis on Bioinformatic
applications, but not much.

Thanks Duncan for the hints.
libxml2.dll is not in my c:/WINDOWS/system32, but in that of a user of
a package of mine. I guess installed by some other application, though
I don't really know what it's doing there (or the consequences of
removing it).
The MSDN site seemed in the long term to point

Would you like existing functions such as mean, range, sum,
colSums, dim, apply, length, and many more to operate on the array of
numbers? If so use an S3 class.
If you would like to effectively disable such functions, to prevent
them from working on the object unless you write a method that spec

No, system32 is searched before the PATH. See

In EBImage I have a very similar situation (well, with more methods). It
would be impossible to use S3 in my case as my data structures are
images and I need at least two dimensions (but in fact use 3), thus 2
variables to dispatch on in [, which are defined for multiple
configurations like int

Should adding PREFIX/library/XML/libs to PATH before system32 solve the
issue as Windows relies on PATH when searching for libs as well?

The XML package relies on libxml2.dll (e.g., bundled with the CRAN
binary) installed in library/XML/libs. Unfortunately,
c:/WINDOWS/system32/libxml2.dll will be found and loaded before
this.
Is there any programatic solution?
Thanks,

In S-PLUS, is() does catch parent S3 classes. It does not
require a setOldClass definition to do so. I would prefer that
R work the same way, to make porting code easier.
I use is() in S-PLUS for both S3 and S4 classes because it is faster
than inherits(). I use inherits() only for testing a ve

Probably, except on Windows.

The print-out of xtable in the following example is wrong; instead of yielding
the correct ci's for the second model it repeats the ci's from the first model.

In S4, an object of class "multipol" has one slot that holds an array.
