title: 'spatialcluster: Spatially Contiguous Clustering with the ''Redcap'' Algorithm'
version: 0.2.1.009
abstract: Groups spatial data into clusters of similar observations, while requiring
  that each cluster forms a single spatially contiguous region. Contiguity is enforced
  by first building a spanning tree from the spatial relationships between points,
  and then cutting that tree into clusters according to a matrix of distances or other
  measures of similarity. Trees may be built from first-order relationships only (direct
  neighbours), yielding a minimum spanning tree, or from full-order relationships
  between entire clusters, using single linkage (nearest members), average linkage
  (mean of all pairs), or complete linkage (furthest members). The single and average
  linkage methods implement the 'Redcap' algorithm ('Regionalization' with dynamically
  constrained agglomerative clustering and partitioning). Results can be visualised
  as maps of clusters, cluster hulls, or trees.
