Hello all, I'm trying to replicate a confirmatory factor analysis done in Amos. The idea is to compare a one-factor and a two-factor model. I get the following warning message when I run either model: "Could not compute QR decomposition of Hessian. Optimization probably did not converge." I have no idea what to do here. I believe posters reported the same problem. It seems

Dear List, My first R function is a rip-off bagging algorithm from pg. 138 of Everitt and Hothorn's "Handbook of Statistical Analyses using R" (HSAUR). I'm using recursive partitioning to develop a set of useful variables in diagnosing ADHD. I'm running this in ESS in XEmacs 21.4.19, R 2.4.1 on Slackware Linux 11.0 with a 2.6 kernel. This is almost an entire script,

Apologies to those for whom this is a cross-post. I posted this to wine-devel before realizing this was the proper forum. Due to resource constraints (75 MHz processor, 1.2 GB hard drive, 16 MB RAM), we recently replaced Windows98 on our daughter's PC with Linux Mandrake, using the IceWM window manager. It isn't quite as flashy as Windows, but it boots beyond the startup screen, which

Hi, I've solved the flash transfer problem changing the flash time in the zapata.conf file, I've set: flash = 200 (the defualt was 750 ms) in the extensions.conf the code is for example: exten => 42,1,Flash() exten => 42,2,SendDTMF(42,250) exten => 42,3,Hangup() now the transfer with flash works correctly. About the question whether my PBX expects a hook flash for

Hi all, I'm testing Dovecot version 1.2.17 on FreeBSD 8.2-RELEASE using ZFS as filesystem. Searching on google I've ridden about some problem concerning indexes and mmap. I wold like to know if this problem persists on the latest releases. Thanks in advance. Roberto Giuliani.

Hi, It would be better to give an example. If your dataset is like the one attached: con<-file("Trial1.txt") ?Lines1<- readLines(con) ?close(con) #If the data you wanted to extract is numeric and the header and footer are characters, dat1<-read.table(text=Lines1[-grep("[A-Za-z]",Lines1)],sep="\t",header=FALSE) dat1 #?? V1 V2 V3 V4 V5 #1? 38 43 39 44 45 #2? 39

Hello dear R members.

Hi, This problem may be related to a configuration problem but I believe it is a bug in the FOP since restarting the FOP server clears the problem. Here is the scenario: Using AgentCallBackLogin and have four agents logged in a call is made to one of the agents directly from an internal phone. Okay so far. Call is hung up and the same extension is used to call another agent okay again, no

Hi.

I've tried to transfer a call using the Flash command, but with my configuration it doesn't work. I have a traditional PBX connected with a zap channel to Asterisk that acts like an IVR: TELCO line --> traditional PBX (FXS) --> (FXO) Asterisk >From the TELCO line I can make a call to the traditional PBX and reach Asterisk, the IVR system on Asterisk answers the call and I can

Dear R users, there is a new version of the package `lmtest' for testing linear regression models on CRAN. Except for a couple of minor bug fixes, there are essentially these new features: o added Breusch-Godfrey test for serial correlation (thanks to David M. Mitchell who provided the initial version of the code for bgtest) o new data sets: mandible measurements in fetuses,

In October of last year Marc Blanchet of the Canadian company Viag?nie made a presentation on how he and others had build IPv6 support into Asterisk and furthermore demonstrated that it worked. Marc Blanchet went into some details on how it was done and the amount of work that had gone into it. A question is this connection: When will these additions make their way into the Asterisk mainstream

Hi all, First, a quick thank you for R; it's amazing. I am trying to fit models for a count dataset following the overdispersed logisitic regression approach outlined in Baggerly et al. (BMC Bioinformatics, 5:144; Annotated R code is given at the end of the paper) but R is returning an error with the data below. Any help in understanding or overcoming this obstacle is appreciated.

I'm interested in further understanding the differences in using many classification trees to improve classification rates. I'm also interested in finding out what I can do in R and which methods will allow prediction. Can anybody point me to a citation or discussion? Specifically, I want to classify remotely sensed imagery where training data is extracted on class membership by the user.

We are trying to use Samba to serve as a file server to support an application requiring relatively low absolute bandwidth, but extremely low latency (think voice over IP). We find that while Samba (with Linux) gives very good performance compared to windows, we find that as time progresses, minimum latency seems to step up while under load from our application. It is almost as if the server is
