Hi. I'm trying to plot a pair of intertwined spirals and an svm that separates them. I'm having some trouble. Here's what I tried. > library(mlbench) > library(e1071) Loading required package: class > raw <- mlbench.spirals(200,2) > spiral <- data.frame(class=as.factor(raw$classes), x=raw$x[,1], y=raw$x[,2]) > m <- svm(class~., data=spiral) > plot(m,

Hi there, I've a problem with rsync - see below. (by the way: I'm using rsync since 2 years now, good work!) my environment: - linux, 2.4, Dual-PIII-1.2GHz, 1 GB RAM. more of these machines. - rsync 2.5.5 - openssh 3.3 the machines are on a lan, so bandwith is not a problem. I sync large directories (about 6 GB growing) between the machines, no problem - memory consumtion of rsync is

In the vcdExtra package on R-Forge, I have functions and generic methods for calculating log odds ratios for R x C x strata tables. I'd like to define methods for fitting weighted lm()s to the resulting loddsratio objects, but I'm having problems figuring out how to do this generally. # install.packages("vcdExtra", repos="http://R-Forge.R-Project.org")

I''m using ActionWebService to allow users to upload files to my rails app. I do this by encoding to Base64. The problem with this is that rails logs the file data so my log file size spirals out of control. Is there any way to selectively disable logging when the web api is invoked? ActiveRecord::Base.silence doesn''t seem too useful here as it''s only called AFTER

Hello, I am using OpenSIPS to register all the users and planning to use asterisk for Auto Attendant, Queues, Voicemail and Conference Bridge. I have a scenario where the signaling does not happen properly: 1) A user from Opensips dials an extension 7000 which is an auto-attendant extension. The call is routed to asterisk to play the auto attendant messages like Welcome and Dial the

I''ve found these two snippets of code useful and would love some feedback. first, .should_have_valid_associations usage: context "A new Product" do specify "should have valid associations" do @product.should_have_valid_associations end end code: (thanks to Wilson/Defiler for converting to rspec) module Spec module Expectations module Should

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")

Hello all, I''m curious as to what development models other people/teams follow when creating web applications. My company has been using the waterfall model( http://en.wikipedia.org/wiki/Waterfall_process) for quite some time now. I''m not completely conviced that it is the right process for web development. I''ve been doing web development for about 6 years now using

Hi all, I am not familiar with writing R extensions. In a C program, I want to create a SEXP and access it in embedded R. How to let the embedded engine know there's a new vector? For example, after creating a SEXP, parsing 'ls()' in embedded R and then evaluating, STRSXP returned will contain the name of the SEXP. Any help would be appreciated. Regards, Spiral [[alternative HTML

does anybody know why dvd use files for audio and video but audio cd's not? What could be the reason for this? e.g. they could make a file for each track and just put them on an audio cd and make cd players compatible with this format. So for me it has always been a mystery why audio cd's work this way. does anybody knows if super audio cd's still work the same as normal ones?

While investigating erratic performance on one our our servers, I'm getting some very odd performance stats coming from vmstat. What initially appeared to be happening is the machine goes into a hard loop in some mod_perl webserver code. Now there still may be an issue with the code, but my code examinations show no possible way this could be happening, but what I'm writing to you

Hi All, I install CentOS 4.4 without additional driver disk. When I partition the disk, I create nothing on the raid 5, and I just create " / " " /boot " and "swap" on the raid 1. And it works. When I create a mount point /storage on the raid 5 and create " / " " /boot " and "swap" on the raid 1. The error comes again, saying that

Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are taken at X,Y and Z planes. See an example here, where I want to plot the measurements for the red, green and blue planes (so the image below withouth the 3d green structure inside)https://www.researchgate.net/publication/258391165/figure/fig7/AS:322947316240401 at

When we assume all variables have all bits set: 2^64 + (2^32 - 1) / 2^32 = 2^32 + 1

Thanks. So after searching 4 hours last night it looks like that there is no R package that can do this right now. Any other ideas or suggestions might be helpful.RegardsAlex On Wednesday, June 21, 2017 3:21 PM, Alaios via R-help <r-help at r-project.org> wrote: Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are

Hello, sorry for writing here because my problem is not a realt bug but may be a solution for many people working with R: I miss the feature for commenting some lines of code at once without writing a bunch of "#" in front of each line. This is interesting for trying out some code. I found some workarounds like IFELSE(FALSE){} and `!`<- function(x) { if (inherits(x,

Hello, I need help with a partial least square regression in R. I have read both the vignette and the post on R bloggers but it is hard to figure out how to do it.
