S4 slot with NA default
...representation(x="numeric"),prototype=list(x=NaN))
[1] "foo"
>
But this is not the correct sense: to me "NaN" means "not a number"
and I want
the sense to be "not available".
Any advice?

wilcox_test function in coin package
Dear All,
I have two simple data samples (no groups or factors, etc.) and would just
like to compute the two-sample Wilcoxon Rank Sum test using the wilcox_test
function contained in the coin package, which is reportedly better than the
regular wilcox.test function because it performs some adjustment for ties.
Would anyone know how to craft a script to perform this task? Much
appreciated.

a != a*1 != a+0 != +a
...is one thing, but "+a" returns
"trim(a)", which might be different.
Also "1*a" would be different from "a" and "a+0"
Does the List consider this to be Good Practice?
Has anyone got comments?

optional setValidity()
...t OTOH, I want the check to be performed "by default" to
stop anyone (me) from being too clever and defining
a non-standard foo object that doesn't meet .checkfoo().
What is best practice here?
Are there any examples I could copy?

[CentOS-announce] Release for CentOS Linux 7 (1503 ) on x86_64

Indeed. And some conspiracy theorist might add this happened after CentOS
"marrying" RH (well, getting tighter relations that is) ;-)
Just a joke to put down everybody's fighting mood (or likely switching
fire onto myself ;-(

RESTful Thinking
Okay, so I am trying to embrace the RESTful approach to web
application design and wanted to get some feedback from others. I
understand that it can be done different ways, I''m just interested to
see what real RESTful theorists think. Lets say that you have an
application that has lists and items on that list. I can see how both
lists and items can be set up as resources. Now, lets say you want to
have an action to both show you the current sorted list* and then
allow you to save a new sort. You would need a custom G...

as.function()

[my real example is very much more complicated than this but
I need this toy one too and I can't see how to modify
as.function.polynomial()
to do what I want]

gsl package on mavericks
...avericks, or it might even lie in newer versions of
the gnu GSL library.
The package gsl_1.9-10.tar.gz installs correctly from source for me on my
system, macosx 10.9.4, R-3.1.1, GSL-1.16, so it is difficult for me to
investigate users' reports.
Can anyone advise?

calculus to study the dynamical behavior of nervous systems and
the computations they perform.
A distinguishing feature of the work group is a close collaboration
between experimentalists and theorists with regard to the analysis
of data and the planning of experiments. The work group will have
a limited number of research lectures, supplemented by tutorials on
relevant computational,
experimental, and mathematical techniques.
The topics covered in the workgroup will maintain continuity with pa...

Does rails support method overloading?
I''ve tried to have 2 methods of the same name (but with different
parameter signatures) and it always seems like the later declaration
tends to win out, does this mean that ruby does not support overloading?
If so what aboutt the .new method? You can either call it as .new (with
nothing) or .new(hash variable). Is it possible to override a specific
instance of the zero parameter

Matrix Inversion
I got the following error:

tb = t(b)
bb = tb %*% b

bb %*% ibb

Error in solve.default(bb) :

Are there any ways to find more information about why it is singular?
Thanks.

I have a paired equation below. Can I solve (x,y) using R.
Thanks!

p=0.114^10
(1-p)*y*(1-x)/x/(1-x^y)=A
A(1+(1-x)*(1+y)/x-A))=B

PDF with computationally expensive normalizing constant
...xecute something like
a <- CalculateNormalizingConstant(a)
and after this, object "a" would then have the numerically
computed NC in place.
Is this a Good Idea?
Are there any PDFs implemented in R in which this is an issue?

This package generalizes the polynom package (which handles univariate
polynomials) to the multivariate case. A short article discussing the
package will appear in the next issue of Rnews, Insha'Allah

Anybody have any objections to that, or any other suggestion of a propper
way to handle this?
If thats the right way, I'll just put it into CVS myself.
