...me modifications in arima.c. I've noticed that a big internal array of double (rbar) is usually sparse and I'd like to add an option to store it as key-value mapping. Is there a library function or some other approach already used inside the R core for key-value mappings? Thanks, Matteo Bertini

Hello, I''m trying to compile wxruby for Ruby 1.9 on Ubuntu Karmic 64 bit, but I can''t get it to work. I''ve already done this for the 32 bit version (on another machine, of course), so I don''t see where''s the problem with that. I thought, I had all neccessary libraries installed, but maybe you know better... After compiling for a long time, rake fails

Hello, I am exploring acts_as_ferret, and the first question that pops to mind is scoping, i.e. how to restrict searches in various ways. For example, I have a Post model with title, content, and user_id as attributes, and I want users to be able to search through their own posts only. Normally, of course, I would do Post.find(:all, :conditions=>["user_id=?", current_user],

If I understand correctly, when you declare that a table/class has_many whatevers, the rails assumption is that there will be a foreign key in the whatevers table pointing back to the ''id'' primary key in the first table.
