I'm trying to read in some data from a .csv format and have come across the following issue. Here is a simple example for replication # A sample .csv format schid,sch_name 331-802-7081,School One 464-551-7357,School Two 388-517-7627,School Three \& Four 388-517-4394,School Five Note the third line includes the \ character. However, when I read the data in I get > read.csv(file.choose()) schid sch_name 1 331-802-7081 School One 2 464-551-7357...

Hi All: This may turn out to be very simply, but I can't seem to add the name of the school to a chart. The loop I created is below that subsets a dataframe and creates a chart for each school based on certain variables. As it stands now, they title includes the school's ID number. Instead, I want to replace this with the school's actual name, which is stored in a variable called...

Hi all. Got a stupid-simple question about associations. I have two models - school and course. There are a fixed number of schools (set up in the migration). Each course is assigned a school and a school will be associated with multiple courses... How do I set up the associations? Do (can) I have School :has_one :course and Course :has_many :schools? Does the schools table the...

Hi, I have a problem in which I have test score data on students from a number of schools. In each school I have a measure of whether or not they received special programming. I am interested in the interaction between school and attendance to the programming, but in a very select set of comparisons. I'd like to cast the test as one in which students in each school who atten...

Perhaps this is intentional, but it seems unlikely: class Person < ActiveRecord::Base belongs_to :school end p = Person.find(:first) p.school # nil p.school_id = School.find_by_name(''High School'').id p.school.name # High School p.school_id = School.find_by_name(''Primary School'').id p.school.name # High School <= Shouldn''t this be Primary School? p.schoo...

...I wanted to use facebooker''s typeahead widget in side the other form builder. I don''t know much about form builders, but I created a file in lib/ doing this: http://pastie.caboo.se/178776 It works great, except that the id''s and class names get messed up. Instead of school_name, I get nilClass_name. The other methods work fine however. Here''s the form: <h1>New School</h1> <%= show_flash %> <% af_form_for :school, :url => schools_path, :html => {:method => :post } do |f| %> <%= f.typeahead :name, @schools, "name&qu...

Hi there, we made a PHP and Impakt2 based web content management system for schools with specific features that work really well for schools. The way I designed it was so there was one central set of source code and an empty (in terms of rows in tables) database structure. To set up a new school i had a script that basically created a new directory in /var/www and then within...

I am very confused about where to put the belongs_to and the has_one (and other relationship identifiers). I have read the RDoc and the agile book many times about this and I think i still see it backwards. Let me outline my app so you have an understanding... I have 2 tables: Schools { id, school_name, address_id } and Addresses { street1, street2, city, state, zip, country } *** this is the way that makes sense to me but it doesnt work ****** Models school.rb has_one :address address.rb belongs_to :school View for School <% for school in @schools %> &lt...

Hello list, I?ve been trying to get OpenBUGS running on my mac using the wine emulator. I can run Openbugs just fine by doing: wine ~/OpenBUGS312/OpenBUGS.exe In the terminal, so OpenBUGS works. When I try to run the schools example using rbugs(), the OpenBUGS process starts in wine, but it just sits there, no log, no script, no output of any sort. The rbugs () call makes the init, data, model and script file, but there seems to be a problem with R piping the script to OpenBUGS, here is my example library(rbu...

Dear R-users, I am trying to use the following code to reproduce results from Prof. Gelman's book, but have the listed error for R2WinBUGS version (the openbugs version is good). I am using R-2.6.1 on windows XP, and all the R packages are most current ones. schools.bug can be found at http://www.stat.columbia.edu/~gelman/bugsR/runningbugs.html . Can anyone help me to figure out what's going wrong? rm(list=ls()) library(R2WinBUGS) library ('BRugs') setwd('C:/bayesian/bda/codes/example_5_5') data(schools) J <- nrow(schools) y <- sch...

Dear List: I have a large dataset of multiple schools. My goal is to produce a separate tex file for each school that plots some of the student achievement scores. Essentially, the aim is to develop a custom report for each school. To accomplish this, I have code for a loop that gets sourced into R and then Sweaves the multiple files to create the in...

...nBUGs from R that is writen by Dr. Andrew Gelman who is a professor from Columbia University. The bugs.R would be very useful for me, and I think many of you know it as well. I followed the instuctions on Dr. Gelman's web to install all of documents that bugs.R needs, but when I try to run the school example the web posted in R, I got an error. Would you please help me out? I am stuck on this for a while and really frustrated now. The program and the error as follow. Thanks a lot in advance!

Greetings all, I have three files that I would like to merge. The first is a student level file that contains the student ID, their school ID, and their country ID. The second is the school file that contains the school ID and country ID. The third is the country file with a country ID. I would like to merge the three together using the common country ID. Of course, what this would mean is that school data be repeated for every...

...ot;meta" analysis. I wonder if weights argument is the right one to use to include uncertainty (standard errors) of "data" into the model. I would like to use lmer(), since I would like to have a "freedom" in modeling, if this is at all possible. For example we can take schools data by Gelman from R2WinBUGS package. As you can see bellow use of weights argument did not had influence on results. I do not know if my specification of weights i.e. 1 / sd^2 is ok. Under least squares one minimizes sum(e^2_i) or sum(w_i * e^2_i) with weighted LS. If I consider that \sigma...

Hi, I am trying to create a variable counting the number of individuals based on two variables. I am able to do it or one variable, but not two. In SAS I was able to sort by two variables and use a first. statement to create the counts based on both.
