Dear sir, I would ask if there are in R some code to generate a random sample from a mvariate student distribution like that one wich generate the multivariate normal one i mean( rmvnorm(n, mu, sigma) Second question : if R can plot density 3Dcurve I don't mean de histogram but de hole density function(normal for example). I use a windows version of The R software Thank you in advance wiyh

Dear R-users, Recently I had to analyze a dataset from household survey. The sample design ensured, that each household in the population has the same probability of being sampled. However the data were gathered from only one adult individual in each household, who was randomly choosen by an interviewer (via "Kish grid"). To equalize the probabilities for each INDIVIDUAL a casewise

Hi, I want to use R for some data mining project , and was wondering if it has any intercative graphical features? For example, is it possible to plot a histogram and be able to select a specific point on it and have all the data about it? or select a specific area in a curve and have all the data about it? or possibilities to zoom out and in? Thank you for your help, Mama Benchaffai School of

Hello, this is kind of a rejoinder to our posting to r-devel "request for comments --- package "distr" --- S4 Classes for Distributions" dating from 01-31-04/ 05:11:50 EST./ To start, we want to thank the contributors of comments and suggestions, which have been quite helpful to us. Also, we want to apologize for being somewhat lengthy in our replies; we hope you could cope

Hello to all. My name is Michal Bojanowski, I'm a Sociology student at Unversity of Warsaw. Recently I've started to learn R when I've found myself frustrated because of inflexibility of SPSS and other "user-friendly" statistical software. As I said, I'm new here, so my question is very simple: I wanted to use a large data set stored in SPSS-format file. I used the

Hi, We have some sample data from the US census, and we know the marginal totals for the population. We need to make the population estimates add up to the correct sums. I have two questions: Is there some package in R which does this adjustment, by any means? Is there some more modern reference for this problem than Deming's 1943 monograph, ``Statistical Adjustment of Data''?

Hello everyone, I encountered the following confusing behavior of 'deparse' and 'substitute' while programming with S4 classes (see example below). It seems like the presence of '...' argument in the definition of the generic generates the problem. I have no clue why, can anyone explain that to me? Are there any "workarounds"? Thanks a lot for your time!

Hello dear useRs and wizaRds, I am currently developing a package that will enable to use administrative map of Poland in R plots. Among other things I wanted to include region names in proper Polish language so that they can be used in creating graphics etc. I am working on Windows and when I build the package it is complaining about non-ASCII characters R code files. I was wondering what would

Dear useRs and wizaRds, I am currently developing a set of functions using S4 classes. On the way I encountered the problem exemplified with the code below. For some reason the 'validity' method does not seem to work, i.e. does not check for errors in the specification of the slots of the defined class. Any hints? My understanding of the whole S4 system was that validity checks are made

At the moment I'm out of the office, but when I return I'll be certain to do that. Note that my solution is different from what you are working on with regexten, though I suspect some of the challenges that I've faced and overcome are not. I'm actually using UltraMonkey for load-balancing and failover of the Asterisk boxes, and my dialplan is set up so that it need not be changed

Hello dear useRs and wizaRds, I encountered the following problem using the hist() method for the 'times' classes from package 'chron'. You should be able to recreate it using the code: library(chron) # pasted from chron help file (?chron) dts <- dates(c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")) class(dts)

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Has anyone any experiance with the FileColumn plugin. I''m trying to create thumbnails, and also alow non picture uploads. Here''s some working code, but if I try and upload a zip, it says ''File invalid image''. Is there anyway of having both image uploads (and thumbnail generation) while also allowing non image uploads? class Entry < ActiveRecord::Base

Would anybody have any numbers on how large a box would be required to convert 100 or 200 SIP calls to IAX2, without transcoding, echo cancel, .. Or a setup with individual IAX2 calls coming on one side, and trunking being used to 1 or more remote boxes on the other side, to improve bandwidth usage ? It doesn't matter if you don't have a test done for exactly 100 or 200 calls, I'm

I was wondering if there is a web front end for clients. By this I mean, is there something I can install on my apache server( wich is running on the same server ) that will alow my users to go to a page, login, and it drop them into there home directory. I have researched WEBDAV but I don't think it has the functionality that I need. Any help is greatly appreciated Wayne Dozier Network

Hello List-Members, Let's say that I have the following code: for (i in c(10, 20, 30)) { for (j in c(200, 400, 600)) { ... ... x <- "something" * (code here) } } * Now, x is some result that I want to put into a results "matrix" that looks like this: 200 400 600 10 20 30 I came up with an ad-hoc solution adding some counters (called

Hi OpenSSH'lers! While using OpenSSH for quite a while, I became annoyed with the inflexible config-file parsing algorithm. I special it did not alow me to express: "Use *no* proxy for host xyz, but *this* proxy for all other hosts". So I had a look at the source an make a quick-n-dirty change, allowing me to use the special ProxyCommand "None" to express "don't

Hi, I'm setting up Asterisk as a voicemail with SER. My problem is, when a caller that is not registered with asterisk (no username and password in sip.conf) it prompts "403, Forbidden" . I need all calls from outside of my network to reach asterisk for my users' voicemails, because anonymous users will surely reach voicemail of my users to leave messages. What do I

I just read some of the discussion on the list about 'bitrate peeling' and remembered an interview of Monty that I have read recently. In it he says that Vorbis uses MCDTs <sp> and that these are theoretically reversable. And now, I learn that theoretically we can use bitrate peeling to make smaller files from larger ones, and that leads to my question. Could I theoretically
