Database abstraction
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

Sorting by score
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.
Greetings,

problems with file_column plugin
1) installation is not as smooth as some other plug-ins. If you follow
the instructions on
http://www.kanthak.net/opensource/file_column/
it makes a directory called trunk instead of file_column. 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

[Weft QDA users] Using WeftQDA for Mailing-List Analysis
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

date
Please, how to transform data from date_select (a set of select boxes)
to one Time? Is there a built-in function? I need something like
create_date(params[:date]) - this would collect all values from select
boxes like date(3i), etc. and create a single date value. This is
automatically done when saving a date into the database, but don''t know
how to use the date in another way.
