Converts Freedom House's Freedom in the World data into standard country-year structure for time-series cross-sectional analysis.

# This script converts Freedom House's annual Freedom in the World data from
# the ugly, table-like Excel format in which it's posted into a data frame in R.
# It is set up to work on future updates, too, and should automatically adjust
# as years or countries are added.
#
# Before running this script:
#
# 1. Open a browser & go to http://www.freedomhouse.org/report-types/freedom-world
#
# 2. Download the file "Country ratings and status, FIW 1973-2013(EXCEL)"

R code for selecting events from GDELT files that look like they might be atrocities (i.e., lethal violence against civilians), summing them by location, and mapping them.
