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 formula
as.phylo(x, data = parent.frame(), ...)
a right-side formula describing the taxonomic relationship: ~C1/C2/.../Cn
.
the data.frame where to look for the variables (default to environment).
further arguments to be passed from other methods.
An object of class phylo
.
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.
