Hi Everybody I've a requirement for one of my operators for an autodialler for which i plan to deploy asterisk (I already have 3 asterisk servers on PRI running very well ! ). The scene is like : Asterisk will call a customer and play a prompt that prompts him to press 1 if he wishes to talk to an agent , If the customer presses 1 then the call gets connected to one of my proffessional agents

Hello, I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network. I didn't find anything in the R documentation for functions to apply on datasets (well, English is not my mother tongue and I have some problems to understand some functions descriptions). Does anybody know where I can find anything about that ? Thank you very much, Thomas

Hello r-proffessionals, this is not a special R-Question, but have anybody a good reason for nonstatistican's why the interpretation of correlations with cases under 20-30 are dangerous !? ...i have got problems explain this without formula's and perhaps anybody know a realworld example what point this problem !? thanks for any suggestion or url/doc etc. Christian Schulz

Thanks a lot for the quick answerd I received and that helped me to solve my first (simple) problem with the plm package. Unfortunatley, here's another one: I do not know why, but I'm unable to estimate a simple model in the form y ~ 1 + x When I try > zz <- plm(y ~ 1 + x , data=mydata) I obtain Errore in X.m[, coef.within, drop = F] : numero di dimensioni errato which means

I need to have all elements of a matrix multiplied by a weight before being post-multiplied by itself, as shown in the forst block of codes below. I can also multiply the matrix by the square root of the weight and then take the outer product. Actually, what I need is this. Denote each row of the matrix by a row vector as xi and each element of the weighting vector as wi. Then, I need the

Hello all We have two very important workstations dedicated to tasks of development and investigation. At the moment we have installed a dual boot platform with CentOS 4.0 and Windows XP Proffessional SP2. In order to do backups of these machines we need to create an image with Norton Ghost 2003. We have worked with Ghost during several years with different platforms (Red Hat, White Box Linux,

Hi all, I've got a script that generates a few moderate-size data frames, and then puts them together into one big data frame at the end in order to write that data frame to disk, so that it may be re-opened later on... I'm trying to trim down memory requirements in this script, so I was wondering if there was any way to append to a data frame already saved on disk (just like

> I disagree. This should be handled by the type legalization > infrastructure. huh... As far as I know, the type legalization is in the SelectionDAG phase, and it is also in the backend. Am I right? or I miss something. > there is currently no support for anything like f32 -> f24 You say "there is currently no support for anything like f32 -> f24", does it means I can

I think Duncan and I disagree. Generally I would defer to anybody else on this list: my experience is backend Target only, with very little poking around the internals. I'm usually asking, not answering, questions here: the 24 bit floats reminded me of the "good old days" at ATI. That said, I think you could make f32/i32 work for your purposes - given the limited types

Hi! I'm trying to do the following. I have monthly a dataset with, among other things, "marketcap", and "return". I want to multiply return by the marketcap of the previous month. How do I do this? In STATA (which I have used frequently in the past) I would simply use an expression of the form return[_n]*marketcap[_n-1] I believe they call this relative

I'm an R newbie trying to do an operation that seems like it should be very simple, but after much playing around with the interface and reading "An Introduction to R" I can figure out how to do it. I have two text files. File1 contains: type n dog 2 cat 4 horse 6 File2 contains: type n horse 1 dog 3 cat 9 mouse 11 I want to read both

Is this a question? You seem to have three possible calculations, have already implemented two of them (?) and it is unclear (to me) what you think the right answer for any of them is supposed to be. -- Sent from my phone.

Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

Hi, I have the file below called happyguys. It is a subset of data. How do I apply the weight variable (WTPP) to this file? Can i just multiply each column (except the first column because it is a record id) by WTPP? If the answer is yes, how do I multiply one variable name by another? Thanks, Nat PROV REGION GRADE Y_Q10A WTPP 83 48 4 7 2 342233324020 115

I have a dataframe of numeric values with 30 ?rows? and 7 ?columns?. For each column, beginning at ?row? 12 and down to ?row? 30, I wish to calculate the ?rolling 12 row product?. I.e., within each column, I wish to multiply all the values in row 1:12, 2:13, 19:30. I wish to save the results as a new dataframe, which will have 19 rows and 7 columns.
