Hi, I'm trying to create a distance matrix. And it works out somewhat ok. However, I suspect that there are some efficiency issues with my efforts. Plz have a look at this: donor <- matrix(c(3,1,2,3,3,1,4,3,5,1,3,2), ncol=4) receiver <- matrix(c(1,4,3,2,4,3,1,5,1,3,2,1,4,5,3,5,1,3,2,4,5,1,2,3,1,4,5,5,1,2,1,3,4,3,2,5,5,1,4,2,5,4,3,2), ncol=4) The above creates my two matrices. I have

I have two models, Donor and Contribution, and have has_many and belongs_to set respectively. My question is regarding creation of associated objects. I''ll let the code speak: me = Donor.find(1) contribution = me.contributions.create do |e| e.amount = 164.00 e.category = Category.find(1) end I thought this was valid, but it doesn''t work properly - it appears to

I''ve been contemplating the utilization of "tags" functionality for categorizing records in my application. For example, a record can have any tag associated with them: volunteer, donor, phone_caller, etc. (Much like delicious) Has anyone already laid out a good architecture for implementing this on the DB, or other medium? I''m sure I can custom build something, but

Full_Name: N. Srinivasan Version: R-2.10.1 OS: Ubuntu 9.10, 64 bits Submission from: (NULL) (68.110.238.141) ,/configure runs fine. But there is no make file mentioned in the INSTALL file. Usually this kind of information is provided in the README file. I am a donor to the R Foundation. Ubuntu uses the Synaptic. It only installs the R version 2.9.0 So, I have to compile R-2.10.1 from the

Hi all, I am not a very proficient R-user yet, so I hope I am not wasting people?s time. I want to run a linear mixed model with 3 random factors (A, B, C) where A and B are partially crossed and C is nested within B. I understand that this is not easily possible using lme but it might be using lmer. I encountered two problems when trying: Firstly, I can enter two random factors in lmer but

All, I would like to thank the latest donor to the CentOS project: Neosurge.com. We have a nice new, shiny server to help get all those updates out faster. http://www.neosurge.com/ Neosurge has plenty of hosting options from normal website hosting to dedicated / co-located servers. And I can vouch for the speed of the traffic into the datacenters. You can definitely get CentOS pre-installed

Dear R listers, When using smooth.spline to interpolate data, results are generally good. However, some cases produce totally unreasonable results. The data are values of pressure, temperature, and salinity from a probe that is lowered into the ocean, and the objective is to interpolate temperature and salinity to specified pressures. While smooth.spline provides excellent values at the

Hi Folks, I''ve just released version 0.9.0. This latest version of Ferret is an alpha release. I have removed the old c extension and Ferret is now running on a fully ported C library. This has allowed some huge performance improvements both with regard to memory and CPU usage. There will probably be a few portability issues to start with. It has been developed on Linux so it should

Hey folks, I''m off to Vietnam for a week on my way home to Australia so I''ll be off the list for a while. Don''t think I''m ignoring you. When I get back I intend to aggressively hunt down the segfault problem that some of you are having in Ferret so that problem will soon be ancient history. If anyone can narrow down a test case that can consistently segfault it

Hi, Just a quick word on this since I was fortunate enough to attend. There were about 18 people, almost all French (if you include the marseillais as French, they may have objections :) Not that I was counting, but there was one female human there. Thanks Mark for your generosity and the good choice in restaurants both this year and last June was it? The souffl? au Grand Marnier was very nice,

Arnaud, my UPS arrived yesterday; thanks for your generosity. I'm using it to power the computer I'm typing on. This moves NUT up a few places on my priority list. In our last email exchange, I believe we agreed on a couple of major points. I want to confirm these before I start modifying the documentation heavily. 1. asciidoc is a good master format for the in-tree documentation. 2.

Hey guys, I''ve just removed the -fno-stack-protector flag from the release so those who had trouble because of this should now be able to install 0.11.2-rc3. If you have any problems with this release, please let me ASAP. Cheers, Dave -- Dave Balmain http://www.davebalmain.com/

Dear Sir or Madam, The group of people with whom I work is now convinced of the usefulness of using R and its packages to meet our needs for statistical analysis. It has become important that R programs and scripts we create today can be run by someone else tomorrow, so need to use version-control. For this to work well, we need to version-control not just our code, but also R and the CRAN

Hey all, I''m back. Some of you are probably thinking that is the longest weeks vacation on record. Well, I''d like to take this opportunity to apologise for my absence and offer a brief explanation. When I got back to Australia I naturally went home to visit my parents, only to find that they have been hit really hard by the drought. They didn''t really tell me just how
