Instructions

• Clone a copy of the repository to your working directory with the command

$ git clone https://github.com/jvpoulos/ga-lottery

• The code uses R version 3.2.2 (2015-08-14). To install this R version on Ubuntu, use the command

$ sudo apt-get install r-base-core=3.2.2-1trusty0

• Open analysis.R in a script editor
  • Verify that all required packages in analysis.Rare installed in your R library
  • Change the file path specified by data.directory to your working directory
  • Change patient.descriptive , patient.robust , patient.qreg , or patient.power to TRUE to run descriptive and auxilliary analyses

• Save your changes to analysis.R
• Open county-maps.R and verify required packages are installed
• Make shell file analysis.sh executable from the Linux/Unix command line:

$ chmod +x analysis.sh

• Execute the file:

$ ./analysis.sh > analysis.txt

• The script will output figures as .pdfs and a .RData file analysis.RData.
  • analysis.txt contains the result of the script and LaTeX table output.
