Fisher test accuracy in doubt
Hi, I noted a discrepancy between R and openepi when I ran a fisher test with
the same matrix. In R:
> a=matrix(c(1,2,6,17), nrow=2)
> a
[,1] [,2]
[1,] 1 6
[2,] 2 17
> fisher.test(a, conf.int=T)
Fisher's Exact Test for Count Data

p-value = 1

lines don't wrap. must scroll horizontally to see/edit a long line in R GUI
I'm facing this problem on R GUI version 2.10.0 on Windows Vista. I have not
changed Windows settings or R GUI settings much except to change from MDI to
SDI.
Someone else reported this problem a few months ago:
https://stat.ethz.ch/pipermail/r-help/2009-April/195714.html
but it wasn't followed up.
I'd change the settings on Preferences, but there's no help explaining the

Problem applying Chi-square in R and Cochran's Recommendations
Sir,
I have a problem here while applying chisquare test to the following Data (
below the subject of this mail) ...when I wanted to test the significance
using three different free statistical packages, here R, EpiInfo and
OpenEpi.
*Only OpenEpi accepts the test based on Cochran's Recommendations. *
R says " chi squared approximation may be incorrect."
Does it mean the same as

Problem with na.omit when using length()
I'm seeing what looks to me like odd behaviour when I use na.omit on a
simple "length" function, as follows.

[LLVMdev] Replacing types, use of refineAbstractType
I'm working on a personal project which involves lowering a superset of
LLVM to "vanilla" LLVM. Part of this involves rewriting types. I'm
working off of the 2.6 code base, so this may have been addressed in a bug
fix.
I'm having trouble with refineAbstractType and recursive types.
Specifically, I'm creating opaque types to serve as placeholders for the

[LLVMdev] Behaviour of NVPTX intrinsic
I have written test.ll as below and ran 'opt' on it as
" opt -std-compile-opts test.ll -S -o -" . But the output shows that there
is code motion around the barrier intrinsics.

[LLVMdev] Behaviour of NVPTX intrinsic
is there any guarantee that the nvptx intrinsic "llvm.nvvm.barrier0" will
not be moved around by opt ?
In other words, can I expect all the instructions above
"llvm.nvvm.barrier0" to remain above it and those below it to remain below,
after all the opt passes are run ?
If that is not the case, is there a way to define such an intrinsic ?
Thanks.

Double integration using R
Hi,
I have a function that I need to do double integration:
\int^T_0 \int^t_0 N(\delta / \sigma \sqrt(u)) (1-N(\delta / \sigma
\sqrt(u))) du dt
where N(x) is a standard normal probability of x.
I start off by writing an inner integral into a function. Meaning
\int^t_0 N(\delta,\sigma \sqrt(u)) (1-N(\delta,\sigma \sqrt(u))) du.
Then calling integrate function on this function. This

Fisher Test in R
Suppose we have the following data set:
Men Women
Dieting 10 30
Non-dieting 5 60
If I run the Fisher exact test in R then what does alternative = greater (or
less) imply? For example:
mat = matrix(c(10,5,30,60), 2,2)
fisher.test(mat,alternative ="greater")
I get the p-value = 0.01588 and odds ratio = 3.943534. Also, when I flip

content_for
Any ideas how I would go about writing specs for views which make use
of content_for?
I''d like, for example, to be able to specify that ABC view places XYZ
in the sidebar, which I do using content_for(:sidebar).
Am I missing something obvious?

Problems with PuppetLabs Yum Repo
Trying to update a RHEL5 x86_64 server
Yum sees puppet-server 3.1.0-1.el5, but does not see puppet 3.1.0-1.el5
I tried cleaning out the cache and trying again, but no luck.
I am going to download the RPM and localinstall it so I am not held up.

strange fisher.test result
A simple question - using the following fishers test it appears that the P value is significant, but the CI includes 1. Is this result correct?

> fisher.test(data.50p10min)

Attribute for Function that does not write to memory that outlives itself
Hi all,
Is there a function attribute or otherwise way to query whether a function
could write to memory that outlives itself?
For example writing to a global or memory passed in via a function argument
would be writing to memory that outlives the function, but writing to a
stack variable or allocation that isn't returned would not.
Cheers,

[LLVMdev] Variable-length Phi-node
All,
Is it possible to create something which has the same effect of a
variable-length phi node in the C++ api. Specifically, create a phi-node
where the number of incoming values is not known at the time of its
creation.
If there is no such way of creating a phinode like that, would it be
possible to create a dummy instruction and perform a replaceAllUsesWith? If
so, what should the dummy

[RFC] Optimization Remark for derived function / argument attributes
Hello all,
During the compilation process, LLVM automatically derives various
attributes about functions and values (for example that a pointer is
nonnull, a function is constant, etc) that are used within a translation
unit.
I propose adding a pass to LLVM that allows front-ends to output derived
attributes. Such a pass would be useful both for developers and end users
to debug programs,

[LLVMdev] Runtime Array-Length
However, how would one allocate the buffer for a string if you did not know
the length of the string at compile time?
For instance, using the api how would one reproduce the code for the
following c++ function?
std::string add(std::string a, std::string b){
return a+b;
}
When allocating the buffer required for the new string, one can determine
the length at runtime, however I do not know how

Exact Maximum Likelihood Package
Dear R users,
I am a mathematics postdoc at UC Berkeley. I have written a package
in a Computational Algebra System named Singular
http://www.singular.uni-kl.de
to compute the Maximum Likelihood of a given probability distribution over
several discrete random variables. This package gives exact answers to the
problem. But more importantly, it gives All MLE solutions.
My understanding is that
