Hi, thanks for reading. Since hours, I am facing a problem and it seems that I am not able to solve it. Let''s say, I''ve got a model called "AnnotationType". This model has got a method called "foobar(x)". It''s just so simple. I can access this method in my unit tests, in the console (all modes), but if I start the server in production mode and try

What do you guys use for design and modeling (and don''t answer pen and paper, because I use those to, they just don''t look so good in a project report ;) ) I have tried stuff like UMLet (free), Altova UMLsomething (pay), dia (no comprende ;) ), NetBeans UML (slow). But none worked just the way I wanted them to. Any suggestions? Christian...

Dear R users, I discovered something strange using the function agnes() of the cluster package on R 3.0.1 and on R 2.14.1. Indeed, the clusterings obtained are different whereas I ran exactly the same code. I quickly looked at the source code of the function and I discovered that there was an important change: agnes() in R 2.14.1 used a FORTRAN code whereas agnes() in R 3.0.1 uses a C code.

This would be very easy to do in a spreadsheet, so I assumed it would be easy to do in Ruby on Rails but I can''t work out how. I

Hi, Does anyone know much about abstract_class? Does it actually prevent instances of the class from being created? Does it disable certain methods? I already know what it''s for, but I want to know what setting self.abstract_class=true actually does. The reason I ask is that I want to use it for a slightly unorthodox purpose. I want a class who''s only attributes are its

This graph -> http://www.math.hope.edu/~tanis/dallas/images/disth36.gif is an example I found at http://www.math.hope.edu/~tanis/dallas/disth1.html created by Maple. Does anybody know how to create something similar in R?
