Asterisk as H323 gateway
Is there anyone who is currently using Asterisk as a production H323
gateway?
And using which combination of asterisk and H323 (chan_h323, chan_oh323?)
The main issue is interoperability with other H323 parties (Cisco AS53xx,
Nextone, etc).
Searching the mailing list it seems that both h323 and oh323 are not so
stable, is it only an impression or using h323 is really not so advisable?

persuade tabulate function to count NAs in a data frame
Hi,
I'd like to ask you a question again. It is basically about data frames, NAs and tabulate function.
I have this data frame. I already used this in one of the previous questions of mine. It intentionally looks this simple, my real 'df' dataframe is much bigger actually and again, I am not willing to annoy anyone with huge databases... So, my database:

[LLVMdev] Adding custom #pragma for clang
I'd like to add a custom #pragma directive in clang for research purposes.
I'm familiar with the LLVM pass-writing interface but new to the rest of
LLVM and clang. I've looked into Simone Pellegrini's work on a #pragma
interface (https://github.com/motonacciu/clomp and
http://llvm.org/devmtg/2013-04/pellegrini-slides.pdf), but I'm in no
position to determine if this approach

tabulate can accept NA values?
tabulate has
.C("R_tabulate", as.integer(bin), as.integer(length(bin)),
as.integer(nbins), ans = integer(nbins), PACKAGE="base")$ans
The implementation of R_tabulate has
if(x[i] != R_NaInt && x[i] > 0 && x[i] <= *nbin)
and so copes with (silently drops) NA. Perhaps the .C could have
NAOK=TRUE? This is useful in apply'ing tabulate to

Calculating frequencies of multiple values in 200 colomns
Hi,
To clarify the default behavior that Boris is referencing below, note the definition of the 'bin' argument to the tabulate() function:
bin: a numeric vector ***(of positive integers)***, or a factor. Long vectors are supported.
I added the asterisks for emphasis.
This is also noted in the examples used for the function in ?tabulate at the bottom of the help page.

Tools for effectively manage Asterisk
Hallo,
we have started playing with asterisk about one month ago, and we do like
very much what we are experiencing.
Now we would like to take some step further towards "standardizing"
installed modules, functionalities, tools etc.
The "wall" we are facing now is: choosing the right tool for * management.
We tried AMP, very powerful but incomplete (CAPI is very important to

How to do a probability density based filtering in 2D?
Hello,
This sounds like a problem to which many solutions should exist, but I
did not manage to find one.
Basically, given a list of datapoints, I'd like to keep those within
the X% percentile highest density.
That would be equivalent to retain only points within a given line of
a contour plot.
Thanks to anybody who could let me know which function I could use!
Best,

How to improve the robustness of "loess"? - example included.
Hi,
I posted a message earlier entitled "How to fit a line through the
"Mountain crest" ..."
I figured loess is probably the best way, but it seems that the
problem is the robustness of the fit. Below I paste an example to
illustrate the problem:
tmp=rnorm(2000)
X.background = 5+tmp; Y.background = 5+ (10*tmp+rnorm(2000))
X.specific = 3.5+3*runif(1000);

how to change the position of xlab in truehist?
Hi,
I'm wondering how can I change the position of xlab in truehist. For example, the following code creats a histogram with 4 bins for my discrete data. I want each bin to be labelled as 0, 1, 2, or 3 in the middle, so that it's clear each bin corresponds to each of the discrete case.
I was thinking of first delete xlab and then add marks myself, but it doesn't look like it's

Including a vector element in an if statement
Hi all,
I've searched high and low on this and found nothing of help. I'm using

a9 is my 100-element vector of incomes. I want pa9 to be my vector that
counts how many of these are classed as in poverty.
My problem is that my command if(a9[i] <

a fast table() for the 1D case
Hi,
table1D() below can be up to 60x faster than base::table() for the 1D
case. Here are the detailed speedups compared to base::table().

(or more if 'useNA="always"')
o With factor/integer/numeric/character of length 1M and 9 levels

match and unique
Is the phrase "index <- match(x, sort(unique(x)))" reliable, in the sense that it will
never return NA?
Context: Calculation of survival curves involves the concept of unique death times. I've
had reported cases in the past where survfit failed, and it was due to the fact that two
"differ by machine precision" values would sometimes match and sometimes not,

Counting entries to create a new table
Hi,
I am an R novice and I am trying to do something that it seems should be fairly simple, but I can't quite figure it out and I must not be using the right words when I search for answers.
I have a dataset with a number of individuals and observations for each day (7 possible codes plus missing data)
So it looks something like this
Individual A, B, C, D
Day1 1,1,1,1
Day 2 1,3,4,2
