1  ec_betadiversity(mat_pa, methods = "bc", site_names = NULL)

mat_pa

Values should be taken among 
site_names 
string vector giving the names of the sites. If 
Currently ra
stands for raw and returns the number of occurrence.
Additionnal values are
bc
: BrayCurtis index,
wi
: Wishart index,
ja
: Jaccard index.
