The function as.phylo.formula
(short form as.phylo

builds a phylogenetic tree (an object of class phylo
) from
a set of nested taxonomic variables.
## S3 method for class 'formula' as.phylo(x, data = parent.frame(), ...)
x |
a right-side formula describing the taxonomic relationship: |
data |
the data.frame where to look for the variables (default to environment). |
... |
further arguments to be passed from other methods. |
Taxonomic variables must be nested and passed in the correct order: the higher clade must be on the left of the formula, for instance ~Order/Family/Genus/Species
.
In most cases, the resulting tree will be unresolved and contain polytomies.
An object of class phylo
