Description Usage Format Source
A matrix including the different conditions (one row for each condition),
to be applied after the p-median procedure. Depending on the aim of the
survey we may need to include other aspects different to environment and
geographic distances. In the example slope
is the slope of the species
area curve, the higher the slope the better the sampling effort. rare
is an index of rarity of the localities and usab
an ordinal variable
classifying the localities according to the amount of open lanscape, ranging
from 1 to 6, 6 being the class with the highest amount of open landscape.
