This package provides a set of functions to assess the strength and statistical significance of the relationship between species occurrence/abundance and groups of sites. It is also possible to check the statistical significance of such associations. New functions have been added (previously distributed in 'resniche') which allow evaluate several niche metrics while accounting for distances between resources on the basis of the similar perception from species (De C<U+00E1>ceres et al. 2011).

Use strassoc for assessing strength of associations and signassoc to assess the statistical significance of the associations (De C<U+00E1>ceres & Legendre 2009). Much more complete functions are multipatt (De C<U+00E1>ceres et al. 2010) and indicators (De C<U+00E1>ceres et al. 2012).
