TestMatrices {metacom}

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:

1) dim=(20 x 20) Randomly generated matrix ('rbinom(400,1,0.4)')

2) dim=(10 x 10) Leibold & Mikkelson 2002 Figure 1b

3) dim=(10 x 10) Leibold & Mikkelson 2002 Figure 2a

4) dim=(10 x 10) Leibold & Mikkelson 2002 Figure 2b

5) dim=(15 x 10) Leibold & Mikkelson 2002 Figure 3c

6) dim=(20 x 20) Presley et al. Figure 3c
