Spatial Point Patterns Analysis

Description

Perform first- and second-order multi-scale analyses derived from Ripley K-function (Ripley B. D. (1977) ), for univariate, multivariate and marked mapped data in rectangular, circular or irregular shaped sampling windows, with tests of statistical significance based on Monte Carlo simulations.
