%description
A tool to define rare biosphere. 'ulrb' solves the problem of the
definition of rarity by replacing arbitrary thresholds with an
unsupervised machine learning algorithm (partitioning around medoids, or
k-medoids). This algorithm works for any type of microbiome data, provided
there is an abundance table. For validation of this method to different
abundance tables, see Pascoal et al, 2025. This method also works for
non-microbiome data.
