Norwegian Continental Shelf Macrofauna Data

Counts of 809 benthic soft-sediment macrofaunal species at 101 sites from five areas along the Norwegian continental shelf. Anderson et al. (2017) used presence/absence versions of these data to illustrate the modified PERMANOVA statistic for heterogeneous dispersions.

Usage

data("norwegianShelf")

Format

A list with three components:

comm

An integer matrix with 101 sites as rows and 809 species as columns.

area

A factor assigning the 101 sites to five sampling areas.

site

Integer site identifiers from 1 to 101.

Details

The published presence/absence analysis is obtained with 1L * (norwegianShelf$comm > 0L).
