similar to: LDA once again

hello, I am using LDA and QDA function of MASS library. I understand Fisher LDA is a method non-probabilistic in nature, so I wonder what happens when I try to predict my test set examples as in: > fit <- lda(labels~., data=train.table, prior=c(.5,.5)) > pred <- predict(fit, data=test.table, prior=c(.5,.5)) Specifically I ask this because in my problem there are 700 examples

hello all, I am trying to print a ps file as part of a function as in: func <- function (..., filename="temp.ps") { # some stuff [...] # plot eval( cat("postscript(\"",filename,"\")\n", sep="") ) plot(...) abline(...) dev.off() # more stuff [...] } but it does not work.

Hello all, I am using libraries (mva,cluster) to produce dendrograms. With 1000 examples the dendrogram gets too crowded, and i am wondering whether there is an option (which i cannot find) to set the number of leaf nodes, like in matlab, and return the plot and the assignment map examples -> leaf nodes. Any suggestion is appreciated. Thanks Edo

Dear R users, I would need some help in building R using minGW in windows 8.1.

Hi all, I have a strange situation on a Asterisk 1.2.17 with FreePBX 2.2.1 Doing a select in the CDR table I noticed there are some calls with billsec greater than duration, duration is always 0 in those calls.

Hello everyone, I'm in the process of running an Icecast server and I would like to know some best pratices. 1. Should I place Icecast on port 8000 or should I change that to one more common (80, 443...)? 2. Should I place the server behind a webserver like ngingx or apache? 3.Can I disable the login interface? what can be disabled? My best guess is to run icecast behind a webserver,

Hi Guys, we're needing a special implementation on Asterisk Our intention is to contribute the development and share back the code to Asterisk community Here is what we need: - An option to Asterisk Dial command which, if used, when calls is answered gives monodirectional audio (Caller should hear the called party but not vice-versa) - A DTMF sequence (maybe handled in features.conf) for

Hi all, I'm having a problem with some Asterisk servers interconnected with each other using IAX (I also tried with SIP without solving the problem) Sometimes, with apparently no reason, some peers become UNREACHABLE (I have qualify=yes in iax.conf) and REACHABLE again as soon as another qualify test is made. Our users are also complaining about audio loss during their calls, apparently

oops, I hit the return and it got sent. All those questions depends on the application you setting up. if your worried about security, isolate the icecast server from your network. We designed a user interface on the company web site fronts the stream servers. The customers get a simple URL for the stream. We use several stream servers some on site and some off, our web server setup to server

I think it's because the website uses Flash as first player instead of using it as a fallback for when the browser does not support modern web standards like the audio tag.

I have been trying to model a labeled graph using ActiveRecord (trunk version). Basically, I have a ''Node'' model which represents a node linking to other nodes. Links (aka edges) are labeled (i.e., have a ''label'' attribute and other behavior). Thus I decided to model edges as an ''Edge'' model and use a ''has_many :trough''
