Loop question
Hi everyone, I am trying to accomplish a small task that is giving me
quite a headache. I would like to automatically generate a series of
matrices and give them successive names. Here is what I thought at
first:
t1<-matrix(0, nrow=250, ncol=1)
for(i in 1:10){
t1[i]<-rnorm(250)
}
What I intended was that the loop would create 10 different matrices
with a single column of 250

Floating simulation error
Hi all, I am running a simulation and a curious error keeps coming up
that stops the whole process. The error is a subscript out of bounds
error, and it seems to happen at different points (floating around)
throughout the looping simulation. Say, for example, it crashes on
sample 1 - iteration 200. I can force it to start again on iteration
202 with all of the same settings, and it is

Calling objects in a loop
Hi everyone, I am trying to calculate a particular variable (vector) from
some previously defined variables in a loop but I am having trouble figuring
out how to get the loop to recognize that it should index for the previously
defined objects. Here is a simplified version of what I am trying to do:

Writing specific columns to a data file
Hi, I have a function that generates some output with 2 columns, but I
only want to write the first column to a file. Is there a way to do
this in the write.table command?
thetaout=write.table(estimatedtheta, file="/Users/morse07/Desktop/R/
Trial/score.dat", row.names=F, col.names=F)
Any advice would be great, thanks!

using "= matrix (...)" in .C calls
Dear R-devel,
I am trying to alter rpart so that it makes additional calculations when
growing the tree.
In the "rpart.s" there is a call to the C routine:
rp <- .C("s_to_rp2",
as.integer(nobs),
as.integer(nsplit),
as.integer(nodes),
as.integer(ncat),

puzzling lm.fit errors
Hi everyone, I am running a monte carlo and am getting an error that I
haven't the slightest clue where to begin figuring it out. The error
is as follows:
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
0 (non-NA) cases
In addition: Warning message:
In ltm.fit(X, betas, constraint, formula, con) :

understanding and resolving seg faults
Dear r-devel,
I am mutating rpart to do calculations on trees.
I am trying to extract information from the tree.
However, I got a seg. fault.
This is the offending line in "rpmatrix.c":
deltaI[0][0] = spl->improve;
(Commenting it out cures the seg fault)
I would like some advice on how to debug this. I have allocated memory
with calloc and deltaI[0][0] should be

Morse Code
This is just curiosity, but I'm wondering why the Morsecode app has remained part of the trunk for all of these years. Is there any practical use for this or is it just an homage to the ghosts of telecommunications past? Does anybody use the Morsecode app for anything interesting? I'm strangely fascinated by this core piece of Asterisk functionality.

Write pure sine to *.ogg directly?
Hello,
I am author of a Morse code training software written
in Perl at http://starling.ws/morse
Currently I output to *.wav and, if on Unix, convert to
*.ogg. And that's okay for a trainer.
But I have desire to upgrade the project to a real-time
communication tool...or at least a Morse code audio
mail routine. And I should like to avoid *.wav.
I'd like some means of writing a pure

Samba 3.0 & 2003 Active Directory Native Mode
Does Samba 3.0.2a release integrate with Windows Active Directory
running in 2003 Native Mode?
The situation is that two corporate departments are joining their
network infrastructure. One department runs several Samba 2.2 servers
and the other is a 2003 Native Mode Active Directory. I understand that
if you upgrade to Samba 3.0 this supports Windows 2000 AD, but it is

Request for code review: the brendan() action
This came up as an RFE during the conference (I believe it''s been logged
as "4012008: brendan() action needed for DTrace Toolkit".)
As everyone here is aware, DTrace is not quite as user friendly as it
could be. For the uninitiated, it can be confusing to run a DTrace
script and not see the expected output. Brendan Gregg has addressed
this in the DTrace Toolkit[1] by

LNT debuginfo-statistics not running?
Hi llvm-dev@
LNT produces statistics and graphs (such as [0]) of debuginfo metrics,
such as number of source variables with locations. It looks like these
haven't run [1] since the move from svn to git -- are there any plans
to get these running again? I find it highly useful to identify what
commits have affected variable locations and how significant an
affect.

Xen vs VMWare comparison paper
One of my customers handed me a copy of this paper and asked why are we using xen if it is so slow...
http://morse.colorado.edu/~tlen5710/12s/VMware.pdf
which is a fairly damning report of performance under Xen in comparison to VMWare, citing worse than 50% overhead of Xen in comparison to physical.
Has anyone seen this paper before?

NET 1.1 framework
Hi,
Is it possible to get an application that requires the MS NET framework to
run under WINE? I see the MONO site. If I build and run MONO would it allow me to
run an application under WINE? Actually I want to do this with a free program
called RUFZ to help sharpen morse code skills. Thanks

Interest in E1 channel banks?
Our company manufactures an E1 channel bank that is approved for use in
Australia (it should also be compatible with Euro standards). It is modular
and available in 10, 20 or 30 analog port configurations. Signal monitoring
and configuration is via Ethernet.
These units are manufactured in low quantities for specific telco
requirements. However if there was enough interest, we would be able to

slow FLAC__file_decoder_seek_absolute()...
Hi,
I checked the archives, but I didn't find anything regarding this
problem. FLAC__file_decoder_seek_absolute takes an incredibly long time
to seek. What can I do about this? How do I fix it?
Here's how I'm calling the function:
if (argc > 2) {
secs = atoi(argv[2]);
seek_point = (FLAC__uint64) secs * sample_rate;
printf("seeking to %d:%02d\n", secs/60,

Large issue - having trouble diagnosing.
Hello,
I am having a lot of trouble with my deployment of Asterisk. I am running
the PBX-In-a-flash turnkey of Asterisk and ever since deployment I have had
many different problems. I have managed to get all issues sorted out as I go
along, until this one that randomly began last week.
We are using Grandstream GXP 2000 Handsets in the office, and at TE110P card
