Hi all - I've been working on a lite ORM and database abstraction package for R. Formatting complex queries by hand has always been an error-prone hassle, so I've tried to do away with that as much as possible, instead, using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this

I''m trying to sort by score but it seems like SortField::SortType::SCORE is 0 instead of a SortType. A test case is attached. Without the C extensions the test passes, so I guess it''s a bug in them. Should I be using it without the extensions? Because if that''s the case I have some other bugs to report.

You have to manually rename it to file_column. I guess this is a minor annoyance but it gives me the feeling that things aren''t quite like other plugins. 2) I get this error: undefined

Hi Alex, Hi Weft-Users! I am looking for a tool for doing a qualitative analysis of mailing-list data. This means I have a *lot* of individual documents (the typical case: around 500-5000 emails), belonging to the same "super-document" (a mailing list). I have looked at several tools and I like that Weft is public domain and written in Ruby, so I want to figure out whether it

I found a bug in ActiveRecord. Being a good netizen, I thought I would write a test to illustrate the bug, fix it, and then submit a patch to the maintainers. However, I can''t run the AR tests.

I made this conclusion by studying

This is automatically done when saving a date into the database, but don''t know how to use the date in another way. --
