Test matrices used to evaluate metacommunity functions

Description

A list of 7 test matrices from two of the foundational papers on the Elements of Metacommunity Structure analysis (Leibold & Mikkelson 2002 and Presley et al. 2010)

Format

A list containing interaction matrices from Leibold & Mikkelson 2002 and Presley et al. 2010:
