Problem with save or/and if (I think but maybe not ...)
Hi,
I recently discovered the R program and I thought it could be useful to me.
I have to analyse data saved as .Px file (x between 0 and 8 - .P0 files have
18 lines at the beginning that I have to skip). New files are generated
everyday.
This is my strategy :
In order to analyse the data, I first want to copy the new data in a
database in MySQL (which already contains the previous data).
So

Using ACE in the ape package
Having a problem running the ace command in ape.
After reading my table into R and then putting the names of the rows in the
table in same order as the tree I can't get ace to run and get the message
Erreur dans as.matrix(x) :

This is the command I am using and each of the vectors used in the

Error in Rcpp/inline (Windows XP)
Hi, everyone,
I am just trying to use Rcpp in my computer, and I would like to try a
simple example from website, but R keeps reporting me error. I am using

Here is the response:

Visual Basic Applications
Hello everyone,
First of all, I apologize for my poor English.
I am a beginner with Wine and I am already astonished by the
possibilities given by such a software. In fact, I got a VB application
that I want to use under my Ubuntu Dapper Distrib. This application is
based on the creation of some objects as :
- scripting.filesystem
- scripting.dictionary
- msxml2.serverXMLHTTP

registering Fortran routines in R packages
Have you tried using tools:::package_native_routine_registration_skeleton()? If you don't like its output, you can easily edit its results and still avoid most pitfalls.
Cheers, Jari Oksanen

Cpus_allowed_list issue in RHEL6.4
Hi All,
I am using RHEL 6.4 on a Dell Server with 32 cores.
But in the Cpus_allowed_list only 30 cores are available. Why is that?
See the snippet from cat /proc/self/status:
Cpus_allowed: 7fff7fff
Cpus_allowed_list: 0-14,16-30
The allowed list is same for the init process as well (see below).
I didn't see this issue, in RHEL 6.2.
Why is that? Is there a way to change it?

Multiple imputations : wicked dataset ? Wicked computers ? Am I cursed ? (or stupid ?)
Dear list,
I'd like to use multiple imputations to try and save a somewhat badly
mangled dataset (lousy data collection, worse than lousy monitoring, you
know that drill... especially when I am consulted for the first time
about one year *after* data collection).
My dataset has 231 observations of 53 variables, of which only a very
few has no missing data. Most variables have 5-10% of

Howto work with a page not generated by the scaffold ?
I am a newbie Ruby and RoR user. In my tests using the turorials that
I found over the web, everthing is working fine and I am very impressed
about RoR framework.
As I am a Delphi developer, without any web development experience,
There is some thing hard to understando and I didn''t find a tutorial
about this.
I wonder how to create a non-scaffold page ? I have customers,

Mixed Conditional Logit with nested data
Hello Everyone,
This is my first attempt to do something in R. As a precursor to a Willingness to Pay analysis, I want to conduct a Mixed Conditional Logit analysis but am unsure how to proceed because of some nesting within my data.
Below is some data and code that illustrate what I’m trying to do. The data are based on responses to a conjoint survey obtained during pilot testing. In the

Can a data.frame column contain lists/arrays?
I'd like to have a data.frame structured something like the following:
d <- data.frame (
x=list( c(1,2), c(5,2), c(9,1) ),
y=c( 1, -1, -1)
)
The reason is this: 'd' is the training data for a machine learning
algorithm. d$x is the independent data, and d$y is the dependent
data.
In general my machine learning code will work where each element of
d$x is a vector of one or

klibc: kbuild improvements
Hi Bryan and other klibc people.
I have taken a stamp on the Makefiles for klibc, this is what
I came up with.
1) No longer recompile on every invocation
2) Correct checking on dependencies
3) Simpler makefile syntax (almost all over the place)
I compile-time tested it only.
Two open issues:
a) Do we realy use .a files for initramfs. I renemed that to the
executable.
b) I renamed

2.0, hourly performance stats
I'm getting constantly high numbers of page reclaims & involuntary
context switches for dovecot/auth.
page reclaims = minor faults = cpu switching back to system-mode, But
why is the auth process doing that so excessively? Same for the large
number of involuntary context switches...
Attached is my "dovecot -n" output.

Posix Problem, difftime
I am having a series of problems using date time data that has been converted into a POSIXt and POSIXlt classes. I have hourly time series data from 1900 that has been converted from text data.
I assume most of my problems come from a mis-underdanding of the POSIX class. My matrix named (aa) for this year is approx 8700 by 4. When I try to calculate the length of posit column ( which is the

Updated ssh-keyscan patch for ssh2 support
In the past 2 months another change occurred in the CVS code that
broke my ssh-keyscan patch. Here's an updated version that tweaks the
changed name (in the Kex struct) and also causes an attempt to grab an
ssh2 key from an older server (without ssh2 support) to fail earlier
and without an error message (Stuart Pearlman emailed me some code for
this).
This patch is based on the BSD CVS

[PATCH] Add SCHEDOP_block_on
This patch adds a facility to block on a particular event channel, for
when a domain needs to block, but cannot enable interrupts. A domain
uses the call something like this:
while (1) {
clear_evtchn_pending(evtchn);
if (check_for_data(evtchn))
break;
HYPERVISOR_block_on(evtchn);
}
The clear of the pending is needed to ensure that any subsequent calls
to block_on() don''t

count each answer category in each column
Hey,
Is it possible that R can calculate each options under each column and
return a summary table?
Suppose I have a table like this:
Gender Age Rate
Female 0-10 Good
Male 0-10 Good
Female 11-20 Bad
Male 11-20 Bad
Male >20 N/A
I want to have a summary table including the information that how many
