Dear UseRs, I have a very simple question. I have a big matrix (say x) including probabilities (values in (0,1)). I have to store in a list the names of the row and the column where max(x) is located. How can I proceed? Thanks in advance for your assistance! mirko

Dear All, I would like to know if the Voung test (Voung; Econometrica, 1989) to compare two non-nested regression models has been implemented in R. Thanks in advance for your assistance, mirko [[alternative HTML version deleted]]

Hello, I'm running debain on my machine with postfix, squirrelmail and dovecot installed. Everything works fine and I'm able to access my mail via squirrelmail and via Outlook with imap. However I want to create subfolders what is not possible. After reading I discovered that I use mbox and that maildir is needed in order to be able to use subfolders. I have created a Maildir folder with

Hi there, I'm quite new to R (and statistics), and I like it (both)! But I'm a bit lost in all these packages, so could someone please give me a hint whether there exists a package for fitting exponential curves (of the type t --> \sum_i a_i \exp( - b_i t)) on a noisy signal? In fact monoexponential decay + polynomial growth is what I'd like to try. Thanks in advance,

Hello, please excuse me if this is not the appropriate mailing list, but I'll give it a try! I recently switched from using Emacs 20.7.1 to XEmacs 21.4, both on cygwin / MS W2K. On Emacs the ESS 5.1.17 was working well, but now, when calling R from within XEmacs, it first asks for the working directory, then says "R process is not running". The ESS buffer holds the

Dear all, this looks pretty much a standard problem, but I couldn't find a satisfying and understandable solution. (A) Given a data frame (or matrix), e.g. x <- data.frame(A=c(1, 2, 2), B=c(4, 5, 5)) and a row of this data frame, e.g. r <- c(2, 5) I need to find one row index i (or all such indices) such that r is at the i-th row in x, that is, the

No, since I'd like to test null: p <= p0 alternative: p > p0. and my understanding is that binom.test tests null: p = p0 (can only be a "simple" null hypothesis according to help(binom.test)) alternative: p > p0 (or p < p0 or p != p0).

Asterisk don't send the "180 Ringing" SIP message to the calling phone when the called party is ringing. How can I force asterisk to send the ringing messages? The option 'r' in the Dial() command or the Ringing() command didn't solve the problem. Mirko

Hi I'm actually running an icecast server to broadcast voice . I'm not broadcasting music at all . Would it be better for me to use speex ? Is there an icecast-like broadcast server for speex ? Would there be a way to read the braodcast stream under windos and MacOs and Linux ? ( Winam or else ... ) Thenks inadvance ... --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg

With recent 2.6 kernels, the command brctl delbr br0 hangs during shutdown, and the kernel prints this message again and again: unregister_netdevice: waiting for br0 to become free. Usage count = 1 I was able to reproduce this problem with several kernels between (and including) 2.6.9-rc1 and 2.6.11-rc2-bk9. I haven't tried later versions than 2.6.11-rc2-bk9 yet. 2.6.8.1-bk2 still works

Is it in bad form to double post to StackOverflow and R-help? Apologies if so. Here's my task: I've got a matrix of means like so means<-matrix(1:10,nrow=2) colnames(means)<-c("a","b","c","d","e") and a matrix of standard deviations like so sds<-matrix(seq(0.1,1,by=0.1),nrow=2)

Hi all, we are writing a cross browser Javascript control that enhances the HTML text input element in order to accept only digits (more or less). Supposing that ''domText'' is the DOM element corresponding to the HTML text input, we wrote the following: Event.observe(domText, "keypress", this.onKeyPress.bindAsEventListener(this)); where this.onKeyPress =

Hi, I am trying to integrate sieve with qmail-ldap. I can't get it to work, and deliver isn't logging anything to the log files (or syslog, if selected). Hence I have got no way to diagnose the problem.

Hi R-helpers, I have been struggling with calculating row and column statistics, e.g. standard deviation. I know that > datac$Mean<-rowMeans(datac,na.rm=TRUE) will give me row means. I have tried to replicate those row means with the apply function: > datac$Mean2<-apply(datac,2,mean) so that I can replace the function argument with "sd" (instead of mean) to get standard

Hello, svyvar from the survey package computes variances (with standard errors) from survey design objects. Is there any way to compute standard deviations and their standard errors in a similar manner? Thanks a lot, Sebastian

Hello, I am planning to build a bigger Internet platform and actually evaluating Java EE and Rails. I have a lot of Java experience and I am quite new to Rails. After playing some weeks with Rails I am sure that it is a mature web framework and I really like the productivtity of Rails. One of the key advantages is that new developers will understand this platform much quicker than all the Java

Hello all, I am new to xtable. I have several datasets in the form of matrices. Consider the following two simple datasets which are 2 x 3 matrices. The rows in both matrices have the same meaning. For example the first row of both matrices are variable 1 and the second row of both matrices are variable 2. dataset1 = matrix( c(1,2,3,4, 5, 6 ), 2 , 3) dataset2 = matrix( c(4,3,5,10, 1, 0), 2, 3)

Hi rsync list! I have a problem with the exclude-from and include-from options. I want sync all jpeg files to an external server - exclude HK and texts folders and jpg inside this folders.

Hi there, as part of a 2 x 2 contingency table analysis I would like to estimate conditional probabilities (success rates) in a Bernoulli experiment. In particular I want to test a null hypothesis p <= p0 versus the alternative hypothesis p > p0. As far as I understand the subject, there are UMPU tests for these types of hypotheses. Now I know about R's "binom.test" but the
