===What's in this package===

R - R code.  Sub-folder GCAT contains the GCAT package

Rails - Rails code

Testing - testing code, data and documents, outside of any regression tests that may be incorporated directly into R packages or Rails applications 



===Getting started===

First you will need to install Ruby and Ruby on Rails. I suggest using RVM to

install them. Documentation for RVM can be found at: http://rvm.io.



You will need: 

Ruby version 1.9.3p194 and Rails 3.2.15

R version between 3.0.2 and 3.2.0.  



The R package is in subfolder R. To install, do the following:

Open a terminal in the R folder

$  sudo R CMD REMOVE GCAT # do this if an older version of GCAT has been installed

$  sudo R CMD INSTALL GCAT



The rails application is in subfolder Rails.  It runs under Rails 3.2.15.  To run it locally using the default Rails WEBrick web server do the following:

Open a terminal in the Rails folder 

$ bundle install

$ rails s

Open http://0.0.0.0:3000 in a web browser
