### Description

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.

### Usage

    elect80

### Format

A SpatialPointsDataFrame with 3107 observations on the following 7 variables.

- FIPS a factor of county FIPS codes
