Share:

Description

Example datasets with 9 different scattering+exposure combinations.

Usage

1

Format

A list with nine elements of class ppp.

Details

A list of 9 point patterns with different degrees of intra-species clustering and inter-species mingling.

The patterns are synthetically produced using a combination of the functions of this package as an energy function of a Gibbs model.

# left column has strong intra-type clustering
# right column has strong intra-type repulsion.
