WMF conversion...
Hello R-Help,
I've got a bit of an issue with WMF's. I am working on WindowsXP and outputting WMF format images. I then take the WMF format images and insert them in PowerPoint. I take the PowerPoint and convert it to PDF.
The WMFs are nothing special. Just the typical x-y plot with a gray dotted grid added and a few matlines. The WMFs, when produced look great! They show

Help me replace a for loop with an "apply" function
...if that is possible
My task is to find the longest streak of continuous days a user participated
in a game.
Instead of writing an sql function, I chose to use the R's rle function, to
get the longest streaks and then update my db table with the results.
The (attached) dataframe is something like this:

replayPlot in loop
Hi,
In order to make a movie-like animation of different graphs
with replayPlot inside a fast loop:
is there a way to avoid the appearance of some
white stripes/streaks between the different calls to replayPlot?
thanks in advance

Variance Ratio test
Hello,
I am looking for a code in R for the variance ratio test statistic (the
Lo and Mackinlay version or any other versions).
Does anybody have such a code they can share or know a library in which
I can find this function?
Basically I have a number of time series which I need to check for
persistence. One other test I can use is the runs test in the tseries
package.
Any help will be greatly

adaptive bandwidth
I am using libopus for my implementation. I wonder if anybody in the list
have any experience on how to make libopus dynamically adjust its bitrate?

adaptive bandwidth
Thanks Dragos,
I assume I will be setting those parameters during initialization of
encoder right?
Question is, if connection gets too lossy, how will opus adapt to it? Can
it automatically shift bitrate down to minimize impact?
Mark from IRC suggests that the app has to be aware of the losses and
change it on the fly.
Has anybody on the list tried this?

I think not so hard question
I'm sorry to bother this list so much
But I haven't programmed in
A while and I'm struggling.
I have a vector in R of 1's and -1's
And I want to use a streak of size Y
To predict that the same value will
Be next.
So, suppose Y = 3. Then, if there is a streak of three
ones in a row, then I will predict that the next value is
a 1. But, if there is a streak of 3 -1's in

Dunif and Punif
Hi,
I am trying to use dunif and runif
however, I have two problems:
if I do
dunif(1:10, min=1, max=10)
I get 10 values, which summed give me 1.1111
I understand that the probability is computed as f(x) = 1 / (max-min)
but in this case it looks wrong: I have 10 values, each one
equiprobable, and the probability for each one should be 0.1 and not
0.11111 (which is, consistently with the

Who is using the jitter buffer?
Oh, I forgot to mention one thing. I currently append a few bits of custom
information to each speex packet which I fetch out with
things like
speex_bits_unpack_unsigned(&sjJitter.current_packet, 1);
It would be very usefull if the jitter buffer didn't actually decode the
packet, but instead returned a pointer to it (or NULL if you should play
silence and -1 if you should repeat the

How do you test for "consecutivity"?
I need to use R to model a large number of experiments (say, 1000). Each
experiment involves the random selection of 5 numbers (without replacement)
from a pool of numbers ranging between 1 and 30.
What I need to know is what *proportion* of those experiments contains two
or more numbers that are consecutive. So, for instance, an experiment that
yielded the numbers 2, 28, 31, 4, 27 would be

Some people asked me lately about how professional Dovecot is.
I purely love that kind of crap. As if presentations meant anything, as
if there aren't all kinds of scholarly work about theoretical perfect
world algorithms and conceptual systems that will never be implemented
and are as practical and effective as wings on a pig. Please.
I'm reminded of the story about how, during the American Civil War, when

fixing shuffle in ogg123
Hi,
There is a bug in the shuffle of ogg123 which was here at least until the
CVS version of 3 days ago. Here's our fix: (it seems to be not perfectly
equiprobable but at least fixes the old one which sometimes gives two
times the same song and never the other song)

permutations of a binary matrix with fixed margins
J?r?me,
As a first attempt, how about the function below. It works (or not) by
randomly sorting the rows and columns, then searching the table for
"squares" with the corners = matrix(c(1,0,0,1),ncol=2) and subtracting them
from 1 to give matrix(c(0,1,1,0),ncol=2) (and vice versa). Randomized
matrices can be produced as a chain where each permutation is seeded with
the previous one.

Blasphemous? any support for a REPO of current edition BIND, et al (e.g., BZ561299)?
Hello CentOS Community Members,
What is RH's be-all end-all justification for staying with an ancient
code base for such important programs as BIND et al?
A similar problem (to BZ561299) was first reported five (5) years ago
on the isc.org mailing list.
Is there any support among the CentOS community for a REPO of current
vintage for such important functions as BIND et al?

[LLVMdev] RFC: GLIBCXX_DEBUG ScheduleDAG Patch
Attached is a patch to fix a GLIBCXX_DEBUG error in ScheduleDAGRRList.
The problem is that calls to CapturePred may reprioritize elements in the
priority queue, violating streak weak ordering requirements.
To fix this, I introduced a reference wrapper for containers to obtain access
to the SUnitVec used by std::priority_queue. When CapturePred runs, it
calls updateNode which does a
