Distance Based Measures of Spatial Structures

dbmss is an R package for 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). It relies on spatstat for some core calculation.

Vignettes

A quick introduction is in vignette("dbmss").

A full documentation is available on the package website. It is a continuous update of the paper published in the Journal of Statistical Software (Marcon et al., 2015).
