| as.phylo.formula {ape} | R Documentation |
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: ~C1/C2/.../Cn. |
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.
