Taxonomy
as.taxo.Rd
The function as.taxo
creates an object of class taxo
that is a sub-class of data.frame
.
Each column of the data frame must be a factor corresponding to a level j of the taxonomy (genus, family, ...).
The levels of factor j define some classes that must be completly included in classes of factor j+1.
A factor with exactly one level is not allowed. A factor with exactly one individual in each level is not allowed.
The function dist.taxo
compute taxonomic distances.
