Covariate model in nlme
Dear R users,
I am using nlme to fit a pharmacokinetic model. The base model is
parameterized in terms of CL, V1, V2 and Q.
basemodel<-nlme(Conc ~TwoCompModel(CL,Q,V1,V2,Time,ID),
data = data2, fixed=list(CL+Q+V1+V2~1),
random = pdDiag(CL+V1+V2~1),
start=c(CL=log(20),Q=log(252),V1=log(24.9),V2=log(120)),
control=list(returnObject=TRUE,msVerbose=TRUE,
msMaxIter=20,pnlsMaxIter=20,pnlsTol=1),

Doubt regarding Feature selection for 'Learning to Rank' algorithms
Hi Rishabh,
I had this feeling before. This is a really nice idea BUT we can not go
ahead with the project which is still not tested in the experimental
settings. Though it may be a wonderful research exercise, I would still
vote to go for the state-of-the-art methods which are completely published
with full details and experimental results. Hope you get my point.
Regards,
Parth.

A Little Help
Hi Rishabh,
I think its better not to expose RankiList to Letor.h and make it better
user friendly. So my suggestion is to convert RankList to the following
statement in this method.
std::map<Xapian::docid, double> letor_score(const Xapian::MSet & mset);
So just convert the RankList in std::map<Xapian::docid, double> format in
the methods where you need to return.

Using stepAIC to produce a p-value for when a particular variable was taken out of the model
Dear all,
I have decided after much deliberation to use backward elimination and
forward selection to produce a multivariate model.  Having read about the
problems with choosing selection values I have chosen to base my decisions
of inclusion and exclusion on the AIC and am consequently using the stepAIC
function.  This post however does not relate to whether or not this is the
correct decision!

CentOS 7.2 libvirtd 1.2.17 bug
Hi,
 
There is a strange issue in the CentOS 7.2 libvirtd 1.2.17 service.
If there is a symlink in the "/etc/libvirt/qemu/autostart/" which is created
before the libvirtd service is started, libvirtd wont start. 
Deleting the symlink from the autostart folder, then starting the libvirtd
service works.
Is this a know issue ? 
 
We have found this on 4-5 servers.

how to use index as model in rails
Hi all,
I''ve used ruby and ferret for the past one month to index resumes. Now I
need a web front-end to the application and the obvious choice turns out to
be rails. But as I''m not interested in using a database and intend to just
use the index, I''m not sure as to how to put it into the MVC framework as
the model implicitly takes a database. Is there a way it can take

hardware decoding on DSP..
Hi all..
I'm a final yr. student at Cardiff University, UK doing BEng Electronic
Engineering. My final year project was supposed be a MP3 digital audio
player. The idea was to stream the file down to a TI DSP board and decode it
and play music.. like in a portable MP3 player. Now, obviously you guys are
aware of the MP3 standards complications and since this is a uni. project,

For loop...
Dear R-users,
I have dataset  with column A and B with1000 values,
For each of column C value (C = seq(1,1000,1), I want to repeat A and B
values and calculate R = A+B*C for each row.
I want to get output as

CentOS 7 libvirt-1.3.0-1 coming to virt-xen buildlogs
Centos 7.2 has updated its version of libvirt to 1.2.17, which ends up
getting installed in preference to the previous virt-xen libvirt
package (1.2.15).
I've merged in the most recent Fedora libvirt package, 1.3.0, smoked
tested it, and pushed it to buildlogs, which can be accessed by adding
--enablerepo=centos-virt-xen-testing (after installing the CentOS 7
centos-release-xen package).

R license: GPL v2 or v3?
For a project I am porting some of R's source code, and I want to
get the license for my project correct, but the top level COPYING file
for R's source states GPL v2, but when using:
    > license()
(which also states GPL version 2) points me towards:
    > RShowDoc('COPYING')
which states GPL v3. Which is correct?
Thanks for clarification (and the amazing amount of

Letor: Post Mid-Term plan
Hello Rishabh,
As per our previous discussion, we will talk each week now about the
project. Please update the timeline/todo/journal accordingly so that we can
check the status on this saturday for this week.
Please remember that this half of the programme is smaller and hence we
would need to be very punctual about the goals.

Mid-term progress
Hi Rishabh,
As per our last progress meeting, I am off for some days and as now its the
time to mid-term evaluation, it would be better to generate a progress
report.
For that, you should first commit the code as it is and then write 2 to 3
page summary explaining the deliverables so far and then the future plan.
Tomorrow is the last day, so better by tomorrow morning, send this across

ubuntu configuration problem "Couldnt get a file descriptior referring to the console"
Greetings to everybody in r-sig-debian land.
I hope I have found the right place to ask this. If not, please refer me on...
I run R 2.9 on Ubuntu 9.04.   I believe many people have seen this
problem, but because the error message is hard to understand, they
have not traced it back to the R install in the distribution.  I think
it ought to be fixed in the R packaging process, but I do not know if

Rcpp, dyn.load and C++ problems
I would go to the source, in this case Dirk Eddelbuettel's (I hope I
spelled it correctly) documentation for Rcpp:
http://dirk.eddelbuettel.com/code/rcpp/Rcpp-attributes.pdf
Note that you need to do
sourceCpp("logistic_map.cpp")
in R instead of building and dyn.load()-ing the object.
