Hi! as my subject says I am struggling with the different of a two-way ANOVA and a (two-way) ANCOVA. I found the following examples from this webpage: http://www.statmethods.net/stats/anova.html # One Way Anova (Completely Randomized Design) fit <- aov(y ~ A, data=mydataframe) # Randomized Block Design (B is the blocking factor) fit <- aov(y ~ A + B, data=m...

I'm running RedHat 9 with a TDM400 (2FXO, 2FXS). Before I implemented Asterisk, some users were using Bell services to set-up 5 way calling: The user would set up a three way call on one line, switch to the second line, set up another 3 way call and then link the two lines together with the Flash key, thus establishing a 5 way call (the user, 2 others on line 1, another 2 on line 2). How can I accomplish the same thing w/ Ast...

Hi, I have an unbalanced dataset on which I would like to perform a one-way anova test using R (aov). According to Wannacott and Wannacott (1990) p. 333, one-way anova with unbalanced data is possible with a few modifications in the anova-calculations. The modified anova calculations should take into account different sample sizes and a modified definition of the average....

Not sure if there is an R way to do this or a regular express way, but here is what I am trying to do. I've got lots of data where the format is HH:MM:SS, but I need to format it like HH:MM:00, i.e. round the second down to zero. What is the best way to do this? Thanks again. Jason

Hi, in implementing a backend for a target we work on, I ended up needing to lower the switch instruction in a very specific way that is quite different from the standard llvm way with the decision trees. The custom implementation wants to get rid of the decision blocks that llvm generates between the actual cases basic blocks and the switch root block. What I do currently is basically deleting these blocks manually and...

hi all, I have a little question about meetme in Asterisk. One of my client ask me that all call can, if is necessary, become conference for 3-4 user during conversation. I think that are 2 way for make this: 1- all call (instead if the users are only 2) are conference 2- using n-way call (http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO) I decide to implement the first way because for the users is the simplest (I think). The problem is that when user call one extension tha...

Hello Probably the easiest way for you is to lower switch instructions via IR-to-IR pass in the way you want.

i want to replace certain values of a matrix. i know how to replace them when the values are in a vector. i tried the same way for a matrix and got this answer: la[la==0]<-1 Error in [<-.data.frame(*tmp*, la == 0, value = 1) : matrix subscripts not allowed in replacement i found a way to do this with "for()", but i think this is the worst way to do it. So is there a better way? Thomas J. Pe...

Hi Being able to do object oriented programming in R is really good. I now started using the Reference Classes and really like it. Though, I have one problem: I cannot find a way to update a method on an existing object. The flexibility that scripting gives (really needed for interactive data analysis) is lost if everything have to be recalculated all the time. For example I would normally work something like this: cl1 <- setRefClass("cl1", ? fields=list(x=&...

Hi Not sure if this is a clang or llvm related question so I'm sending to both mailing lists. Anyways, I have few questions regarding size and execution time of instrumented code: We are trying to run code coverage on memory limited hardware and investigating both (generating gcov output using -coverage and the llvm's own way using -fprofile-instr-generate -fcoverage-mapping clang flags) In my...

Hello, What is the best way in rails to check a session hash value for nil ? I have a session hash called user (session[:user]) that sometimes I have to check for a certain variable like session[:user].email. however the following always results in an error if session[:user].email and I always have to do if session[:use...

Hello, dear R users. I've already sent a question here, but I'm not sure that it had been read. I need to visualize classification of my numerical data based on 2-3 factors. As I suppose, the best way is a tree. With an orbitrary function at the ends (leaves), or at least with means of my data at the ends. What is the way to do it? As I found, ctree offers binary classification, but it that the only way? Of course, tree is not only way, may be you could offer other ways. Thank you.

Hi all, I'm doing a 3-way ANOVA like this: summary(aov(formula('FP ~ (lum * obj * man)3 - Error(vp/(lum * obj * man)3)'),data=dataf)) But in the output I only get 1- and 2-way effects, like this one: Error: vp:obj:man Df Sum Sq Mean Sq F value Pr(>F) obj:man 1 1.5291e-34 1.5291e-34 5.7011 0.0542 . Residuals 6...

Apparently asterisk's default way to a 3-way conference lets the user in the middle hangup and the other parties stay on the conversation. This is great some times but it creates quite a bit of problems when trunks dont have disconnect supervision or when trying to do accounting and billing on the user. Here is the 'normal'...

Is there a way to save EVERYTHING in R? Hi all, Could you please shed some lights on me about this? I am trying to see if there is a way to save EVERYTHING in R to a file, something like "save.image"... But "save.image" doesn't save environment variables such as those properties that a...

...e subject of representing relationships between a single model object. Basically, I want a User to be able to mark others as Friends, Contacts, etc. The caveat is that User A can mark User B as a Friend but that doesn''t mean User A is marked as a friend by User B. It can either be a one-way relationship or two-way relationship. Right now I''m confused as to whether there is a "proper" way to do this. I''m looking at Single Table Inheritance, HABTM, and now the new Polymorphic Associations in Edge Rails. The main thing that''s confusing me is that w...

...Rails for about a year and a half now. I''ve been using Rails'' built in testing framework, and it''s fine... until I really have to start dealing with the fixtures. I am currently working on an application that really focuses on selecting data using complex logic. The only way to test the application in a meaningful way is by using a large number of fixtures. This has become a real nightmare to manage and I almost am spending more time keeping the fixtures up to date than I am coding or testing. So, I took a moment, stepped back, and took a good look at how I could I cou...

Is there a way using dovecot facilities to block an IP from attempting POP3 connections (similar to the sendmail access file for smtp connections)? I usually do this at my border firewall, but if there's a quick and dirty way in dovecot to do this, it'd make life a little simpler. Thanks steve campbe...

I''m just wondering what the best way to go about loading my API keys from the database is ... Should I simply place them in the ENV variable? Is there a way better way to go about this?
