Spatial patterns of conflict in Africa 1966-78
afcon data frame has 42 rows and 5 columns, for 42 African
countries, exclusing then South West Africa and Spanish Equatorial Africa
and Spanish Sahara. The dataset is used in Anselin (1995), and downloaded

is the SpaceStat ‘rook.GAL’, but is not the list used in Anselin
paper.nb reconstructs the list used in the paper, with
inserted links between Mauritania and Morocco, South Africa and Angola
and Zambia, Tanzania and Zaire, and Botswana and Zambia.
is the coordinate matrix for the centroids of the countries.
This data frame contains the following columns:
an easting in decimal degrees (taken as centroid of shapefile polygon)
an northing in decimal degrees (taken as centroid of shapefile polygon)
index of total conflict 1966-78
country id number as in paper
