Mean nearest taxon distance
Calculates MNTD (mean nearest taxon distance) for taxa in a community
mntd(samp, dis, abundance.weighted=FALSE)
samp |
Community data matrix |
dis |
Interspecific distance matrix |
abundance.weighted |
Should mean nearest taxon distances for each species be weighted by species abundance? (default = FALSE) |
This metric has also been referred to as MNND (mean nearest neighbour distance), and the function was named mnnd in picante versions < 0.7.
Vector of MNTD values for each community.
