Hi, Does anyone know of an R ORM (Object Relational Mapper)? I'm thinking of something similar to sqlalchemy (http://www.sqlalchemy.org/). Alternatively or additionally, can people offer suggestions about managing relational databases from R. I'm currently using postgresql, but would like a flexible solution that works across different databases, hence the enquiry about ORMs. Please

Hello Railists, I have a piece of Ruby on Rails code that has a complex SQL query (well, not that complex, but as far as I know beyond the ORM capabilities) and for my taste it has too many strings and harcoded values. I''d like to improve it as much as possible, so my question is open ended, what else can I do to improve it? Some particular issues I have - Is there a way to get a table

I am looking for an open-source SQL modeling tool to use with MySQL, MariaDB and PostgreSQL. Does anyone have a favorite?

Me and some colleagues are planning to write a textbook together ("Statistics using R") where the target audience for the book is psychologists and students of psychology. We thought that it might be a good idea to use a Wiki when writing the text. Is that a good idea? Does anybody have any experience in that direction? What alternatives are there? The tool (Wiki) would have to be

I''ve been trying to use Rails on a database where the biggest datawarehouse-style table doesn''t have a primary key. It really doesn''t make sense and just adds extra unnecessary space. I do have, however, a column that I normally use to search on (IP) that returns many rows. The table also references several other tables through rails-friendly foreign keys. Simple AR

I''m curious -- how many of us came to Rails from other branches of the OO world -- Java, C# -- and how many of us came from the design or non-OO scripting worlds? Reason I ask is that I''m finding Rails a blast and very productive, but I think one reason is that I already cut my teeth on MVC and ORM during two years of writing apps with J2EE/Struts/Hibernate. And in Javaland, it

I have bought the book, and are working with chapter 18 (about Ajax). I don''t get the List application example to function as expected. When i fill inn a name, and presses "Add Item". The button gets gray, the text "Adding..." is coming up, and the item is being written in the top of the page, but then it freezes here. I uses the newest rails, installed with Gem, and

Hi there, I love the acts_as_* family that rails uses. I''ve also found I can create something similar by dropping the following code into my activerecord classes: class MyClass < ActiveRecord::Base class << self alias_method :count_with_unapproved, :count end def self.find(*args) options = extract_options_from_args!(args) if options[:conditions].nil? options[:conditions] =

Hello, I'm looking for a textbook that can explain some of the math behind the intro-to-intermediate stuff like ANOVA, multiple regression, non- parametric tests, etc. A little background: I took an intro stats course last year and would like to further my education. Being as that was the highest (and only) stats class the local community college offers, it looks like I'm on

Hi folks, I am working on my student internship to USA, california and would like to attend a R Advanced Programming course while I am in USA. Where can I find such a course. I am new to this list. Trevor O'brien >From Ireland. [[alternative HTML version deleted]]

Hi, I'm trying to learn all that I can about exception handling from the compiler's point of view. Although much has been written about compiler theory in general -- parsing, code generation, you name it -- I can find almost nothing on the specific problem of exception handling support. In fact, the most informative document I've been able to find so far is "Bill's

Dear Group, I am an economics student starting with PhD work in London. As preparation I would like to get to know R a little bit better. For Stata there are tons of books, however, can you recommend a book for R? I have some substantiated econometrics knowledge, so it should be more a how-to book.

Are there any plans to move the schema definition from migrations to the model, where it should be? Like og does, which I think is used by the ruby Nitro framework...

I''m using merb as an application server backend for a client application, the goal is to be able to handle thousands of parallell sessions (not parallell requests). It will use sendfile to send files. The controller uses an singleton that saves sessions in a hash that is memory resident cross requests, but isn''t persistent otherwise. I''m using ActiveRecord since there

Hi, Matthew, all nice to hear about interest from Packt Publishing for LLVM I think there are a lot of professionals in this mailing list, who can be an author of the book. But writing a good book demands a lot of time, so that's why there are not so many responses (and also maybe because of well-formed and updated online documentation, which can be a good replacement for the book).

Hello all- I would appreciate any guidance that can be provided. I am new to R and am using it exclusively in a statistics program I am undertaking that mainly references Minitab. My focus is on data modeling and further more multivariate data analysis as much of my work in involves chemical measurements from custom sensors using all sorts of transduction methods. I am looking for a

Daniel, Tobias, Renato and myself have been looking a little bit at the potential underlying reason for why http://llvm.org/perf/ is instable, and have found some clues. I want to share them here to give people with more experience in the frameworks used by LNT (flask, sqlalchemy, wsgi, .) a chance to check if our reasoning below seems plausible. Daniel noticed the following backtrace in the

Hello, Min. I suppose I should ask you this: what do people need to know before working with LLVM? Could a book work with that and link it to LLVM specifically?
