⚠️There's a newer version (2.9-2) of this package.Take me there.

dbmss (version 2.2.3)

Distance-Based Measures of Spatial Structures

Description

Simple computation of spatial statistic functions of distance to characterize the spatial structures of mapped objects, including classical ones (Ripley's K and others) and more recent ones used by spatial economists (Duranton and Overman's Kd, Marcon and Puech's M). Relies on spatstat for some core calculation.
