is it possible to implement a recursive foreign key association like that? i''m writing a vocab app, where i want the vocab table to have an id and two foreign keys, word1 and word2. the word table will have an id, a word-string, and a language i''m trying to do this as follows: class Vocab < ActiveRecord::Base belongs_to :word belongs_to :word class Word < ActiveRecord::...

Env: R 2.8.1, Win Xp, Eclipse/StatET In a .Rd file, I have an example containing the lines: # calculate Y M, using polynomial contrasts trends <- as.matrix(VocabGrowth) %*% poly(8:11, degree=3) colnames(trends)<- c("Linear", "Quad", "Cubic") [At the risk of a long message, I'll append the complete .Rd file at the end of this message, in case this was triggered by an error elsewhere.] I can run R CMD build and R CMD IN...

Hi, I have a set of covariance matrices but not the original data. I want to carry out some exploratory factor analysis. So, I am trying to construct a covariance matrix list as the input for factanal. I can construct a list which includes the cov, the centers, and the n.obs. But it doesn't work. I get an error that says "Error in sqrt(diag(cv)) : Non-numeric argument to mathematical

Sorry, I'm sure I'm not using the appropriate vocab here, which is undoubtedly why I can't seem to find a fix to this (hopefully very easy) problem. Suppose you have a factor abc <- factor(c(2,2,3,4,7,7)) And you want to know what the number in the nth spot in that would be abc[1] [1] 2 Levels: 2 3 4 7 shows the correct label of the firs...

Hi everyone, I looked around the list for a while but couldn't find a solution to my problem. I am storing some results to a simulation in a list and for each element i have two separate vectors(is that what they are called, correct my vocab if necessary). See below Version1_<-list() for(i in 1:5){ Version1_[[i]]<-list(First=rnorm(1),Second=rnorm(1)) } What I want is to put all of the elements' 'First' vectors into a single list to box plot. But whats a more elegant solution to the below? c(Version1_[[1]]$First,Ve...

...hey said that since it works on local files its not their problem. Not the most helpful answer but its the only one I've got. I'm running with posix locking = no. Still nothing.

(The problem doesn't occur under NFS.) Any ideas would be appreciated. Jack

Hi, i am working on the jailhouse[1] project and am currently looking at inter-VM communication. We want to connect guests directly with virtual consoles based on shared memory. The code complexity in the hypervisor should be minimal, it should just make the shared memory discoverable and provide a signaling mechanism. We would like to reuse virtio so that Linux-guests will eventually just work

...py. Usually the guest OS does a bounce buffer into your shared region. Goodbye performance. Or you can play remapping tricks. Goodbye performance again. My preferred model is to have a trusted helper (ie. host) which understands how to copy between virtio rings. The backend guest (to steal Xen vocab) R/O maps the descriptor, avail ring and used rings in the guest. It then asks the trusted helper to do various operation (copy into writable descriptor, copy out of readable descriptor, mark used). The virtio ring itself acts as a grant table. Note: that helper mechanism is completely protocol...

Hi, I am trying to find a way tp update attributes in a habtm association. I am trying to use the code from ticket #2462, but as my association_class_primary_key_name seems to be empty the generated sql code is corrupt. I hope thats not a problem of my model that this variable is empty. What would you recommend to update those attributes (rails 1.1) THANKS!!! -- Posted via

Quick informal poll: what is everyone's favorite text editor for working with R? I'd like to hear from people who are using editors that have some level of direct R interface (e.g. Tinn-R, Komodo+SciViews). Thanks! --j -- Jonathan A.

I''ve kept this one on the back burner for a while, waiting for it to mature before attempting to use it, and now having seen OpenBSD ship with IPSec I''m getting a bit impatient =). What is the status of IPSec for Linux (and more specifically RedHat)? By this I mean I just did some www browsing/etc and found about a half dozen different implimentations, ranging from NRL, to a

We have new drafts of CMML 4.0 as a text codec and ROE as an xml stream abstract, subsuming the authoring support in CMML 3.1 and earlier. Another thing we talked about at LCA is a how to specify relationships between the various streams in Ogg so that a server, muxer or player can make intelligent decisions about the contained tracks. The general idea is to use the (http-style) Message

Hi all, I''ve been thinking about the whole validator/relationship speccing issue, and I came up with a suggestion, which I''d love to get some feedback on. The full article is available at http://www.inter-sections.net/ 2007/10/19/what-to-test-and-specify-and-where-to-do-it/ , with the relevant bit being about halfway down, but here''s the gist of it: 1.
