How do I assign boolean (o,1) values to a column?
...!! I'm trying to assign boolean values to a column in a matrix depending on the number of times present in another column. I have no clue, I have been 2 days looking for a way, if somebody knows what kind of functions I need to use I will really apreciate it. example: Color Type Mark1 Mark2 Mark3 Red high 139 P alpha blue low 140 P alpha Green high 141 S alpha Yellow low 142 S beta Red high 143 P gamma If we only take into account columns Mark1, Mark2 and Mark3. I would like to ask R to write another column with 0=one; 1=mor...

echo cancellation: the never-ending quest for truth
Asterisk apparently has five echo cancellation algorithms: STEVE, STEVE2, MARK, MARK2 and MARK3. The current default appears to be MARK2. My question is, has anyone had any experience with any of the others (other than MARK2), and is there some conventional wisdom as to when to use one over another?

more cpu intensive echo cancellers ?
Hi, I've had some decent luck with the mark3 echo canceller from the zaptel driver, echos on about 20% of the calls, people I've called say I sound great now, but our side hears echos. I was wondering if there was any way to tweak the current software cancelers into using more CPU (and hopefully doing a better job, close to a hardware can...

Best echo canceller?
hi! In your experience what is the best choice for echo canceller ? Which one should work better: STEVE, STEVE2, MARK, MARK2, MARK3, KB1 ?

odd 'digital' sound artifacts
...bove, but they sound the same. When using the aggressive echo suppressor, it seems like those artifacts cause a really loud buzzing sound to come out of the cisco phone, pretty much made using the aggressive canceler impossible to use, it's too bad because it worked the best out of all of them, mark3 works ok but still gives echos on at least 20% of the calls. I thought they might be caused by IRQ sharing, so I pulled one of the TDM400P cards out and made sure the remaining two were on their own IRQ, the artifacts were still there. I've also tried running a kernel with all the low-latency...

Echo problem with TDM440P and ADSL Line
...2 - Analog with ADSL It's installed with two analog lines one of them have a ADSL splitter. The location are Spain, i load the tdm driver with opermode SPAIN, i read that this will set the correct impedance for the line. I compile first time zaptel with ECHO_CAN_MARK, but also i probe MARK2, MARK3, KB1 and ECHO_CAN_MG2, with no result for the Line that have the ADSL. The aggresive make good with the adsl line, but get really extrange sounds across the conversation. I don't know the milliwat test line here on spain to setup the gains correctly (If any body knowsm send it, :) ), so i c...

Connection TDM400P to UK PSTN
I'm a complete Asterisk novice and have an installation based on the Asterisk@HomeCD. I've installed my TDM400P with 2 x FXO & 2 x FXS, but every time I try to dial out, I get a message "No circuits available". Can someone confirm the pinouts for connecting the FXO's to a UK BT Line - I have RJ11 connectors on the back of my TDM400P card, so ideally I'd like to

Echo observations and some questions
...eading the source code. While I suspect that I could decipher the algorithms used in the other cancellers if I were to spend several weeks studying the problem, the authors already know the answer to this and should clue us in, even if only with comments in the source files. The rest - mark2, mark3, steve2, steve3 - have no identification of the algorithm at all. This should be fixed right away, since proper selection of an echo canceller is dependent upon knowing the algorithm. You need to know what the training performance, tail length, wighting mechanism, etc. If they were identifie...

Question on echo's for Canadian Asterisk users ...
Has anyone has issues with echo using a Wildcard with a PRI from a major Canadian Telco? (Bell, Telus, AllStream, Sprint, Group Telecom). We are using a T1 from GT that is giving use annoying echos whenever a SIP/IAX2 client calls a local analog line. Calling cells phones is no issue since its digital. Regardless, there should be no issue with echo on a PRI at all. NOC at GT is telling us

RFD: With echo and other distortion, can ulaw/alaw line quality ever be good enough for faxing?
Folks, I've been following recent discussions regarding echo and echo training with much interest, since it's a problem we've never been able to eliminate here. We're facing two challenges presently, and they may be related (or not): a) Cisco 7960s in the office here echo back to our staff, but the customer hears decent sound. b) We've yet to be able to pass faxes through

Font size in geom_dl (using ggplot2)
Hey everyone, I am an R-newby... so sorry for bothering you with simple-to-solve questions;) I have the following issue: trying to add labels to my scatterplots (with geom_dl in ggplot2). Everything works fine, but after checking every resource I do not find a way to change the font size of my labels. I tried size, cex, fontsize at every position... but it always stays the same. ggplot()+
