Isometric Log-ratio Transform applied to a phylogenetic tree
Calculate balances given a rooted phylogeny.
Parameters
table :FeatureTable[Frequency | Composition]
The feature table containing the samples in which the ilr transform
will be performed.
tree :Phylogeny[Rooted]
A rooted phylogeny of feature identifiers that defines the partitions
of features. Each tip in the hierarchycorresponds to the feature
identifiers in the table. This tree can contain tip ids that are not
present in the table, but all feature ids in the table must be present
in this tree. This assumes that all of the internal nodes in the tree
have labels. This tree may contain polytomic nodes (i.e., nodes with
more than two children), in which case they will be bifurcated.
pseudocount :Float, optional
The value to add to zero counts in the feature table.
