R in Nature
Hi all,
We've just had a paper accepted for publication in Nature. We used R for
95% of our analyses (one of my co-authors sneaked in some GenStat when I
wasn't looking.). The preprint is available from the Nature web site, in
the open peer-review trial section. I searched Nature for previous
references to "R Development Core Team", and I received no hits. So I

Publication & Project: Verificarlo: checking floating point accuracy through Monte Carlo Arithmetic
Hi,
We have recently published a paper on floating point accuracy analysis
through Monte Carlo Arithmetic. We also released the open-source tool
Verificarlo (https://github.com/verificarlo/verificarlo) that relies on
LLVM for instrumenting floating point operations.
Could you please add our paper to http://llvm.org/pubs/ ?

Bias in R's random integers?
...her languages? Would
a patch providing such an algorithm be welcome? What concerns would need to
be addressed first?
I believe this issue was also raised by Killie & Philip in
http://r.789695.n4.nabble.com/Bug-in-sample-td4729483.html, and more
recently in
https://www.stat.berkeley.edu/~stark/Preprints/r-random-issues.pdf,
pointing to the python implementation for comparison:

Thanks!

bias issue in sample() (PR 17494)
Before the next release we really should to sort out the bias issue in
sample() reported by Ottoboni and Stark in
https://www.stat.berkeley.edu/~stark/Preprints/r-random-issues.pdf and
filed aa a bug report by Duncan Murdoch at
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17494.
Here are two examples of bad behavior through current R-devel:

m <- (2/5) * 2^32
x <- sample(m, 1000000, replace = TRUE)

Is R the right choice for simulating first passage times of random walks?
...ou have pointers for those?
I glanced at simFrame [5] and read `?simulate` but could not understand
it right away and think that this might be overkill.
Do you have any suggestions?
Thanks,
Paul

Help on R strucchange package
Hello,
Im using strucchange package in R software in order to apply Bai and
Peron (1998, 2003) structural break tests to a set of n=1671
observations with a constant term (no AR terms).
For that purpose I have read several papers, for instance Validating
Multiple Structural Change Models An Extended Case Study, in which
its aim is to replicate the results from Bai and Perron (2003) in R

Publication of an llvm-based tool that protects against fault injection attacks
Hello,
My team and I have recently published an LLVM-based tool at
“Cryptography and Security
in Computing Systems 2016” (CS2), and we would like to add it on the
list of LLVM related publications.
The goal of our tool is to automatically protect the code being compiled
against fault injection attacks
