Newbie here. Many apologies in advance for using the incorrect lingo. I'm new to statistics and VERY new to R. I have a "nx2" matrix , I want to sort the values based on the average of 2 columns and put k lowest (or highest) values in bin1, second k high/low values in bin2, and so on (bins would be of the same dimensions). I should also know what the first index (or position) of

I have a simple Car model with fields maker:string and model:string. For the controller I planned to just have an index action do all the work: class CarsController < ApplicationController def index if request.post? @car = Car.new(params[:car]) @car.save end @cars = Car.find(:all) end # def create # @car = Car.new(params[:car]) # @car.save # redirect_to :action => :index # end end The corresponding view l...

...irtain UI. [The background] Now let say I have a object "Car". Apart from having basic attributes like car name, model, etc etc, tt has a list of "parts" that a car has. This essentially means i have two models (or tables in db) "Car" and "Part" and "Cars_Controller" and "Parts_COntroller". [The Problem] Now I want to develop an edit interface for this scenario. The edit interface has two tabs "General Car Details" and "Car Parts". Now I understand that when I select to "edit" a car. This will take me...

A new function in my heplots package wants to use a non-exported utility function in the car package, df.terms, but this depends on other non-exported functions. From the Writing R extensions manual, I thought I could do this via (in my NAMESPACE) importFrom(car, car:::df.terms, car:::df.terms.default, car:::is.aliased) but I get: ** preparing package for lazy loading Error : objects

Estimados miembros de la lista, Estoy trabajando con la función spin del paquete knitr y no puedo entender por que a pesar de usar #+ para iniciar cada chunk no reconoce el inicio de un nuevo chunk al menos que incluya texto entre cada inicio de chunk.

Any rpart user: I am trying to construct an rpart tree using a subset of the data and it will occasionally fail when predicting a categorical response variable. The reason that rpart fails is that the subset does not contain each of the categories present in the original data. For example, in the car.test.frame example, a subset that has all the categories except "Small" will not

...t, in this case, for: Car.new("student_id" => student.id, attributes_of_car) which does it assign the car to the student. Is that simply a bug in the docs? And now comes has_many, which is where the real confusion begins. Take the same scenario, but now a student can own one or more cars: class Student has_many(:cars) end class Car belongs_to(:student) validates_presence_of(:student_id) end When I do student = Student.new(attributes_of_student) student.cars.build(attributes_of_car1) student.cars.build(attributes_of_car2) Until now, everything is fine, except that the car...

I've been inspired to look at the R source code by some strange timing results that I wrote about on my blog at radfordneal.wordpress.com (see the posts on "Speeding up parentheses..." and "Two surprising things...". I discovered that the strange speed advantage of curly brackets over parentheses is partially explained by an inefficiency in the evalList and
