similar to: error correcting a signal

Hi, I wondered why the pages on the Wiki are immutable?? The page http://wiki.xensource.com/xenwiki/XenStoreReference contains an errorneous Python example and I want to correct it. Does anybody have access to the Wiki? (and yes, I just created an account) Cheers Andreas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Using dovecot 1.2beta (but earlier versions should behave similarly) we have a problem in conjunction with empty To: headers and the RT request tracker. RT sends mail out using Bcc: and no To: header at all. To make some mailers happy one can configure to send a dummy To: header, which we do. Our To header looks like: To: "AdminCc of rt Ticket #123456":; The message_address_parse

Hello. Consider the response-variable of data.frame df is constant, so analytically perfect fit of a linear model is expected. Fitting a regression line using lm result in residuals, slope and std.errors not exactly zero, which is acceptable in some way, but errorneous. But if you use summary.lm it shows inacceptable error propagation in the calculation of the t value and the corresponding

hi, i have a tricky situation here and and don't know where to start with the solution. i happened to set up a linux system, but i had to install the base system on another machine. i used e2fsprogs 1.30-WIP (30-Sep-2002) for this. now the machine is up and running, but i have to use e2fsprogs 1.27 (8-Mar-2002). it's a debian system and i wanted to stay sane & stable, hence using

Hello there, I am creating a series of images using levelplot but I also want to overlay a contour for a particular value as reference. Here is the levelplot command for the image: print(levelplot(d~x+y,data=t,cuts=20,scales=list(draw=F),xlab=NULL,ylab= NULL,col.regions=heat.colors(100)[100:1]),split=c(1,1,1,1),more=T) and then to add the contour plot (I only want a contour at level 5):

Hello, I don't understand the description / help-text for the numericDeriv() function. Why is there a new environment used? And what is meant with an environment here? Is it similar or the same as a local workspace, like an environment in functional languages? And why is it needed here? numericDeriv could just calculate the difference bewtween two values and divide this difference by the

I've got two brand-new, fully-patched XP SP2 clients who are suffering a mysterious malaise. These two machines will cause a smbd panic when printing or accessing files on a somewhat random basis. Now, the puzzling thing is that three other XP SP2 clients, including one of the exact same configuration, have no issues whatsoever. I've basically ruled out hardware failure on the server,

Maybe you shifted the signal too much. If the mic signal is just one single sample *ahead* of the playback signal, then there's no cancellation possible (because the system is not causal). Be careful with that. Otherwise, if could simply be dropped frames. Jean-Marc On 2009-12-30 07:06, Marco Pierleoni wrote: > The problem is that now I have two files very similar (one for mic, the

Hello, are there people outside who use R for analysis of wind-measurement data (meteorological or for planning of wind power stations)? Are there already scripts/modules available for analysing and displaying/plotting wind data in the way it is done in projection/planning of wind power stations? If not, would it be of interest to use R for this, and therefore adapt data-logger output to R (by

My wife just got laid off - the recession has hit her law firm hard. This means my priorities have shifted to either finding more paying work myself or helping her find another job. This means the timeframe for a finished repo conversion just got more uncertain, as I may not be able to work steadily on it for a while. -- <a href="http://www.catb.org/~esr/">Eric S.

In the R source, nmath/pnorm.c contains the code for a rational function approximation for the normal cdf. These constants are listed: const double a[5] = { 2.2352520354606839287, 161.02823106855587881, 1067.6894854603709582, 18154.981253343561249, 0.065682337918207449113 }; The source file cites a paper by Cody (1969) and states that these

Hello Gurus, I'm using one of the function, i.e. extractModelParameters, from the MplusAutomation package to read parameters fromMplus out files into R. I have 360 cells and each cell has several out files (max. 100). I'm extracting the model parameters from each cell and doing subsequent calculations, primarily, on 'est.' column. The following code demonstrates how I'm

The problem is that now I have two files very similar (one for mic, the other for speaker). If I play them together I can hardly say that they are two different file for most of the file length. When I try to cancel the echo, I obtain as output almost the same input. The update_foreground variable is always 0. I don't get the conditions which must be fulfilled in order to have

Hello, I have strings with date-/time-data from a logfile. For a sort-by-time (and other time-related analysis) I need something to convert the times to the Unix-epoche-time (better also with parts of seconds). Is there something that does that job (or a similar conversion) in R? TIA, Oliver Bandel

Folks, I've scoured the website and googled, but can't find a definitive answer: What's the difference? OK, the site says 1.4.26.1 is latest stable. Site also says 1.6.2.0-beta4 is latest beta. So what are the others? TIA, David A. Bandel -- Focus on the dream, not the competition. - Nemesis Air Racing Team motto Visit my blog at:
