Asterisk, QSIG and Tenovis PBX?
Hi,
we are still trying to properly connect a Tenovis PBX to an Asterisk server
(asterisk 1.2.6, libpri 1.2.2, zaptel 1.2.5, Digium Wildcard TE110P), this
time with QSIG.
Calling from a Tenovis phone to a SIP phone (i.e. traditional phone ->
Tenovis PBX -> QSIG -> Asterisk -> SIP phone) works with the following

double boostrap with clusterApplyLB
Dear R-Users,
we are using a linux-cluster with RMPI and the snow package.
We would like to do a double boostrap.
We have a general function that implements the first boostrap (the outer) and
we are wondering if we can include another bootstrap (the inner) in the
same general function including another clusterApplyLB.
For example:
general function = function(...) {

validate.lrm - confidence interval for boostrap-corrected AUC ?
Hi
Does anyone know whether the rms package provides a confidence interval for
the bootstrap-corrected Dxy or c-index?
I have fitted a logistic model, and would like to obtain the 95% confidence
interval of the bootstrap-corrected area under the ROC curve estimate.
Thanks.

boostrap astronomy problem
Hi,
I am an astronomer and somewhat new to boostrap statistics. I understand
the basic idea of bootstrap resampling, but am uncertain if it would be
useful in my case or not. My problem consists of maximizing a likelihood
function based on the velocities of a number of stars. My assumed
distribution of velocities of these stars is:

rpmstrap/rpmbootstrap to boostrap CentOS 5
Hi,
Is there any working script, similar to deboostrap, for CentOS 5?
I have found rpmstrap [1] at RPMforge.. but only works for CentOS-4, and
appears that's out of date.
thanks!

Boostrap p-value in regression [indirectly related to R]
Hello All,
Despite my preference for reporting confidence intervals, I need to
obtain a p-value for a hypothesis test in the context of regression
using bootstrapping. I have read John Fox's chapter on bootstrapping
regression models and have consulted Efron & Tibshirani's "An
Introduction to the Bootstrap" but I just wanted to ask the experts here
for some feedback to make

Help with permutation function from Turner et al. 2010 (Ecology)
Hello,
I'm using R code that includes a residual permutation that was written as a supplement to the paper:
Turner et al. 2010. A general hypothesis-testing framework for stable isotopes ratios in ecological studies. Ecology 91:2227-2233.
The supplemental code is available at: http://www.esapubs.org/archive/ecol/E091/157/suppl-1.htm

How to create unique factor from two factors? + Boostrap Q
This might be easy but I'm very new to R and this question doesn't seem to
have any nice keywords that bring up relevant search results when I search
the CRAN search engine. Therefore, I'll plead (as I have in the recent
past) Newbie status.
I have a data frame with two factors (Factor 1 and 2) which together specify
another unique level. I want to create a third factor in the

Unexpected parameter problem using rsaga.geoprocessor() {RSAGA}
Hello,
I discovered SAGA, an interesting free GIS, a few days ago and now, I
would like to use it from within R 2.6.2 using the RSAGA package. I read
the documentation for this package and thought that I understood it
correctly for trying to call some of the SAGA modules. For getting the
information on the usage of and arguments required by the SAGA command

conducting GAM-GEE within gamm4?
Dear R-help users,
I am trying to analyze some visual transect data of organisms to generate a
habitat distribution model. Once organisms are sighted, they are followed
as point data is collected at a given time interval. Because of the
autocorrelation among these "follows," I wish to utilize a GAM-GEE approach
similar to that of Pirotta et al. 2011, using packages 'yags' and

S-code for piecewise regression
Dear R-helpers,
a S-code for piecewise regressions was provided by Toms & Lesperance
(2003) Ecology, 84, 2034-2041 (paper can be found on the web).The code
is quite complete with different types of transitions around breakpoints
and model selection fonctions.
It doesn't work directly under R due to some "translation" problems I
guess. However I reckon that it would be a

Salut Alex.
En fait je me suis rendu compte de mon erreur à propos de "HSCROLL", ça marche correctement. La scrollbarre apparaît et fonctionne bien. La dernière fois j''ai eu l''impression qu''elle ne marchait pas, car cela peut arriver que la dernière lettre de la ligne de charactères qui s''affiche soit un peu coupée par la "VSCROLL".

Tail area of sum of Chi-square variables
Dear R experts,
I was wondering if there are any R functions that give the tail area
of a sum of chisquare distributions of the type:
a_1 X_1 + a_2 X_2
where a_1 and a_2 are constants and X_1 and X_2 are independent chi-square variables with different degrees of freedom.
Thanks,
Klaus

[LLVMdev] Boostrap Failure -- Expected Differences?
The saga continues.
I've been tracking the interface changes and merging them with

of llvm-gcc but the object files from stage2 and stage3 differ:

Fitting with error on data
As this forum proved to be very helpful, I got another question...
I'd like to fit data points on which I have an error, dx and dy, on each x
and y. What would be the common procedure to fit this data by a linear model
taking into account uncertainty on each point? Would weighting each point by
1/sqrt(dx2+dy2) (and taking dx and dy as relative errors) in a lm() fit do
the job? I would like to

What steps to take
Hi list
I'm attempting to list windows shared printers in Unix. That's really all
that I need and I can't install Samba on the machine I need to list the

Certainly for a C novice.
Which is why I want to ask if there is anyone out there who

Comparing two different 'survival' events for the same subject using survdiff?
I have a dataset which for the sake of simplicity has two endpoints. We would like to test if two different end-points have the same eventual meaning. To try and take an example that people might understand better:
Lets assume we had a group of subjects who all received a treatment. The could stop treatment for any reason (side effects, treatment stops working etc). Getting that data is very
