Theoretical Data Set used in Ricotta and Pavoine (2015) in Ecological Indicators
Description
The data set was used in Ricotta and Pavoine (2015) to show how the coefficients of multi-site dissimilarity that they developed can be applied to data.
Usage
data("RP15EI")
Format
The format is a list of 4 data frames. Each data frame gives the presence (1) and absence (0) of 10 species (columns, S1-S10) in 8 plots (rows P1-P8). These data are characterized by different levels of nestedness and turnover in species compositions between sites.
M1
: Intermediate nestedness and turnover.
M2
: Perfectly nested pattern.
M3
: Very high species turnover.
M4
: Random configuration.
