Hi all, I have a very large binary vector, I wish to calculate the number of 1's over sliding windows. this is my very slow function slide<-function(seq,window){ n<-length(seq)-window tot<-c() tot[1]<-sum(seq[1:window]) for (i in 2:n) { tot[i]<- tot[i-1]-seq[i-1]+seq[i] } return(tot) } this works well for for reasonably sized vectors. Does

Dear R gurus, As part of finding initial values for a much more complicated fit I want to fit a function of the form y ~ a + bx + cx^d to fairly "noisy" data and have hit some problems. To demonstrate the specific R-related problem, here is an idealised data set, smaller and better fitting than reality: # idealised data set aDF <- data.frame( x= c(1.80, 9.27, 6.48, 2.61, 9.86,

Hello, I have configured my TDM01B Card (1 FXO Port ) as follows (below) but it will not pick up an incoming call. Any suggestions/tools to see what the problem is? I have looked at zttool where this line changes but I don't understand what it means (The last digit changed from 0 to 1) Total/Conf/Act: 4/ 1/ 1 /etc/zaptel.conf fxsks=4 loadzone=nl defaultzone=nl

I am dying here with linphone (not sure if it is crap software or just me being an idiot) but out of the box debian installations of two linphones fail with a "Got SIP response 415 "Unsupported Media Type" back from 192.168.1.3" Can anybody recommend a particular SIP soft phone that broadly satisfies the following criteria? 1. Run on linux. 2. Simple to use and setup. 3. Is

I find that when asterisk answers the phone, the initial second or so is lost. I can imagine that echotraining can do this, but this is between SIP phones and I don't think there is any echotraining enabled? BTW. Asterisk is definitely playing sounds that first second (The CLI would indicate that it would play a beep but I just won't hear it). Any comments appreciated. Pieter

I am looking for some help at removing low-frequency components from a signal, through Moving Average on a sliding window. I understand thiis is a smoothing procedure that I never done in my life before .. sigh. I searched R archives and found "rollmean", "MovingAverages {TTR}", "SymmetricMA". None of the above mantioned functions seems to accept the smoothing

Can anybody recommend a reseller in Europe (Netherlands) for modules for the X100P (FXO and FXS modules)? Cost, support are important. Also, what is a reasonable price for an X100P in Europe? Is there a difference in price between OEM and Boxed versions? Thanks, Pieter

Dear R users, I?m trying to optimize simultaneously two binomials inequalities (used in acceptance sampling) which are nonlinear solution, so there is no simple direct solution. Please, let me explain shortly the the problem and the question as following. The objective is to obtain the smallest value of 'n' (sample size) satisfying both inequalities: (1-alpha) <= pbinom(c, n, p1)

I'm trying to do a linear discriminant analysis on a dataset of three classes ("Affinities"), using the MASS library: > data.frame2 <- na.omit(data.frame1) > > data.ld = lda(AFFINITY ~ ., data.frame2, prior = c(1,1,1)/3) Error in var(x - group.means[g, ]) : missing observations in cov/cor What does this error message mean and how can I get rid of it? Thanks! Pieter

However, in the stylesheet I define a image to use for my site background. eg: html, body{ background-image: url(mysite_background.jpg); padding-top:

Hi all, I want to set the advertised value of MTU for virbr0 interface on a Fedora 21 host to 1454 to accommodate the installation of new VMs for testing purposes. The aforementioned host is an OpenStack VM actually, which explains the need for a lower than 1500 MTU. I noticed Pieter Hollants' patch to set dhcp-option=<number>,"<value>" for an interface, but

All, Given the amount of NULL-pointer dereference vulnerabilities in the FreeBSD kernel that have been discovered of late, I've started looking at a way to generically protect against the code execution possibilities of such bugs. By disallowing userland to map pages at address 0x0 (and a bit beyond), it is possible to make such NULL-pointer deref bugs mere DoS'es instead of code

Hi list, I have tried with all my might to get a samba3 server (Ubuntu 12.04.1 LTS) to join a Windows 2003 domain as a member server, without any luck. I have used,from memory, the official way of doing this (aka, from the samba.org website). No matter what settings I use in smb.conf, the server always joins as a domain controller. This doesn't seem to break the domain how ever. All I am

hey, is there a way to run tinc on a (linux) box, with a public ip, but on which i don't have root privileges ? the server just connects nodes (behind natted firewall) & relays their traffic, so no need for tap/tun interface on the box itself. ptr_ -- http://www.L45.be/voidpointer 0493 52 5009

Dear Shorewall list, I need to connect a firewall to various remote sites (VPN''s) at the same time, but i do not have control of any of the remote subnets and/or the given IP address: The firewall is just a client in all of the VPN''s. So, as i see it, the remote subnets (mostly rfc1918) are doomed to get into conflict when they happen to be connected at the same time. For

Hello, I did make a stupid fault: not commiting changes to version control :-( After the installation of puppet-dashboard, I added a recipe to add report = true to puppet config files on clients. Now all Puppet clients don''t update because of an error... What can be the various reasons for an ''400'' error?? I guess it has something to do with rights. Jun 28 09:52:36 pm

I am trying to get a program running under wine that needs to connect to a flexlm license server. Unfortunately I get denied when authentication because the license is a 'windows' license and I am running the program from a linux platform. Is there a way to make wine authenticate as windows? I am using the 'windows version' of the program, so I am assuming that there is
