JRI and error message from R_isMethodsDispatchOn
Dear R users,
I have a small project written in Java and need some statical tools.
Therefore, I used JRI (in rJava package) as an interface between R and
Java to write some wrappers for my work. However, I received error
message from R while I have more than one java method which wraps R:
Error in .Call("R_isMethodsDispatchOn", onOff, PACKAGE = "base") :

S4 method dispatch: coercion of arguments with setAs defined
Hi list,
I've got a class B that contains a slot obj of class A. I'd like to be
able to call all the methods of class A directly on objects of class B
as if I had called the method on slot obj. This without overloading all
methods of class A to work on class B.
I don't define B as an extension of A, because I want class B to also
work with objects of classes that inherit from

Do *not* pass '...' to NextMethod() - it'll do it for you; missing documentation, a bug or just me?
Hi,
although I've done S3 dispatching for more than a decade now, I think
I managed to overlook/avoid the following pitfall when using
NextMethod():
If you explicitly pass argument '...' to NextMethod(), you will
effectively pass those argument twice to the "next" method!
EXAMPLE:
foo0 <- function(...) UseMethod("foo0");
foo1 <- function(...)

Denoiser level and AEC problem
Hello,
Is it possible to adjust the level of the denoiser ?
In an old beta, before you change the aggressiveness of the denoiser, it
works very well with the noise of a car, a road etc... but not now.
The AEC too works very well in a old beta, but now, I think there is a
problem... I have tested it with the same sound card (WB 16000).
In any case, your project is the best VOIP library in this

Denoiser level and AEC problem
Hello,
The denoiser was good with a car noise or a raod noise before the r11739.
But for some situation, the actual version is perfect. That's why I think
that if we can adjust the agressivity of the denoiser, we can respond to all
of the situations. Maybe two parameters should be enough : high or low.
For the AEC, I have to test with older versions because it's another person

MySQL transactions not working in unit tests?
I just installed acts_as_authenticated into an app and one of its unit

transactional fixtures turned on and MySQL InnoDB engine being used.

Exportar datos en formato de Excel
Hola.
En mi caso, no he podido resolver los problemas con el Java para usar

Ok, I see that in the split_cb_shape_sign_unquant function, that each
coefficient is tied to it's position in the nb_subvect exc coefficients.
Honestly, I have problems understanding what exactly the codebook search
works like. If you have the time to to

FULLTEXT search in MySQL on rails
I tried adding a FULLTEXT search index to a table of mine in MySQL,
only to discover that the InnoDB table format doesn''t seem to support
this feature. Switching to the MyISAM table type seemed to work, but
I seem to have some recollection that ActiveRecord transactions aren''t
fully atomic on MyISAM tables. Is this true or am I just remembering
wrong? If so, does anyone have
