Hopkins burnt savanna herb remains
A 20m square is divided into 40 by 40 0.5m quadrats. Observations are in tens of grams of herb remains, 0 being from 0g to less than 10g, and so on. Analysis was mostly conducted using the interior 32 by 32 grid.
Data on 25,357 single family homes sold in Lucas County, Ohio, 1993-1998 from the county auditor, together with an nb neighbour object constructed as a sphere of influence graph from projected coordinates.

Spatial patterns of conflict in Africa 1966-78
The 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 from before adaptation. The neighbour list object africa.rook.nb is the SpaceStat ‘rook.GAL’, but is not the list used in Anselin (1995) - 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. afxy is the coordinate matrix for the centroids of the countries.
A data set for 1980 Presidential election results covering 3,107 US counties using geographical coordinates. In addition, three spatial neighbour objects, k4 not using Great Circle distances, dll using Great Circle distances, and e80_queen of Queen contiguities for equivalent County polygons taken from file co1980p020.tar.gz on the USGS National Atlas site, and a spatial weights object imported from elect.ford - a 4-nearest neighbour non-GC row-standardised object, but with coercion to symmetry.

(Package: spdep) :
Corrected Boston Housing Data
The boston.c data frame has 506 rows and 20 columns. It contains the Harrison and Rubinfeld (1978) data corrected for a few minor errors and augmented with the latitude and longitude of the observations. Gilley and Pace also point out that MEDV is censored, in that median values at or over USD 50,000 are set to USD 50,000. The original data set without the corrections is also included in package mlbench as BostonHousing. In addition, a matrix of tract point coordinates projected to UTM zone 19 is included as boston.utm, and a sphere of influence neighbours list as boston.soi.
