Hi there - I have been trying to generate some simple stats and save the results to a file. My data looks like this: x y z exp 0 3 5 1 2 11 10 1 4 4 5 1 7 6 4 1 11 1 2 2 5 7 1 2 3 3

Hello all, Sorry for this email not directly related to R developement. I just come from a nice demonstration session from Scitegic about their Pipeline Pilot (PP) software, and especially their 'R collection' which brings R calculations into the software (http://www.scitegic.com/documents/RStats_Collection.pdf). I looked carefully on the way they do it: they pass data from PP to R

I'm looking for an efficient way of removing zero-variance columns from a large matrix. Any suggestions? Thanks, - Moises [[alternative HTML version deleted]]

Hi all - I am trying to tune an SVM model by optimizing the cross-validation accuracy. Maximizing this value doesn't necessarily seem to minimize the number of misclassifications. Can anyone tell me how the cross-validation accuracy is defined? In the output below, for example, cross-validation accuracy is 92.2%, while the number of correctly classified samples is (1476+170)/(1476+170+4) =

I'm using the following command to run R in Windows "Rterm --no-save --no-restore < "Rscriptfile" > "Rstdoutfile" How can I capture the text sent by R to stderr in a file? Thanks, - Moises [[alternative HTML version deleted]]

Hi, I'm a developer working on an application for Windows XP and have been using the Win32 API call FileLockEx() on shared files (writing or reading). This has been working fine, but we now have a customer where this causes the following error when trying to lock a file on a samba network drive (it works fine if the file is local or on a windows shared drive): LockFileEx returns false.

Thierry, thanks for this, this is a bug in utils:::.format_person_as_R_code(). This calls deparse() on the elements of the person object with the default width.cutoff = 60. As your comment exceeds this width, the erroneous formatting is produced. The simplest reproducible example I could come up with was: p <- person(".", comment = c(foo = ".....................",

Dear all, I think I found a bug in utils::format.person when using style = "R" with a vector of comments. The comment section is not parsed properly. Please find below the mwe and the session info.

Hello all, I''m new to Ruby and have come across this project that seems to be the most mature scheduling project for Ruby. I''ve had some brief experience with Quartz for Java and was wondering if there were any plans to provide an option to save scheduled jobs into some sort of data store? If not, is that something the project would be interested in? Has someone

I was doing some unit testing today and came across something that surprised me. Either I am confused, or destroyed objects persist in memory when doing unit testing. To explain: I have a model, Author, which ''has_many :web_resources''. One type of "web resource" for an Author is the authors website. So, to facilitate easy creation/lookup of websites for authors, I

hello, Is this a bug or feature? You have a few domU configs saved in /var/lib/xen/save/ Don''t ask me how mine got there. You make some changes to those configs, plus a few others. When you reboot and do xm list, the changes to the ''saved'' configs revert while the non-saved cfg changes stick. This was driving me bonkers, until I noticed that xen was keeping some

Hello, I would to know if if does it possible to have something like this : acts_as_authentic do |c| c.login_field = :user_name c.crypted_password_field = :user_passwd c.persistence_token = :pertok end Using the "pertok" field instead of the "persistence_token" field ? Or say to Ror to use the "user_passwd" as "persistence_token" field.

Hi, In advance, sorry, I am not sure if it''s the right mailing list to ask that, but as my question is half-way between Xen and trousers, I thought asking in both mailing lists would not be too much.... I am currently having a little problem finding out how to make work my seal/unseal things... Running a Debian Lenny on top of Xen 3.5 unstable. with vtpm management enabled on my

All, I am looking into open source idea's for something I play with on the closed source side. What I am thinking is to get two Asterisk PBX's behind a single SIP proxy to load balance calls inbound, and potentially outbound to an external sip provider, with the potential of multiple provider type lines (SPA3102, and a sip provider) that allows the call to persist. What I am

Hello I am working with 3 host machines each running xen with shared NFS storage. I am working on automatic load balancing if one host is over utilized and another is under utilized by measuring the utilization from xentop. I am facing a problem after migration of VM. I am setting the flags ( 1| 8| 16) in order to do live migration, persist VM on destination, undefine host from source. After

Hi, I'm looking to get an ISO of FreePBX or AsteriskNOW installed on a USB that I can boot from and also be able to save my changes. Is this possible? My search on web doesn't seem to find anything useful. For now I don't have the option of having a spare machine or creating a partition on my existing one for my experiments with Asterisk. My end goal is to have chan_mobile

Hi! I'm aware that (host side) vnetX are created when VM boots. But I'm trying to figure out a way ti create a persistence in vnetX names. What I mean is, say, I want to associate VMs vm0 to vnet0, vm1 to vnet1, vm2 to vnet2 and so forth, no matter which order the VMs are booted. I looked around network XML format, but did't find something... Since I'm using Open vSwitch as

Yes. Since the 0.9.7 release, the configuration XML is transferred to the other side too. However, by default, migrated domains are
