⚠️There's a newer version (2.01-45) of this package.Take me there.

splancs (version 2.01-42)

Spatial and Space-Time Point Pattern Analysis

Description

The Splancs package was written as an enhancement to S-Plus for display and analysis of spatial point pattern data; it has been ported to R and is in "maintenance mode".
