n_subtaxa: Number of subtaxa per taxon
In zachary-foster/taxa2: Classes for Storing and Manipulating Taxonomic Data

Description Usage Arguments See Also Examples

Get the number of subtaxa per taxon.

1	n_subtaxa(x, subset = NULL, max_depth = NULL, include = FALSE)

`x`	The object to get subtaxa for, such as a taxonomy object.
`subset`	The subset of the tree to search. Can be indexes or names.
`max_depth`	The number of ranks to traverse. For example, `max_depth = 1` returns only immediate subtaxa. By default (NULL) information for all subtaxa is returned (i.e. subtaxa of subtaxa, etc).
`include`	If `TRUE`, include information for each taxon in the output.

Other subtaxa functions: subtaxa()

# Generate example data
x <- taxonomy(c('Carnivora', 'Felidae', 'Panthera', 'Panthera leo',
                'Panthera tigris', 'Ursidae', 'Ursus', 'Ursus arctos'),
              supertaxa = c(NA, 1, 2, 3, 3, 1, 6, 7))

# Find number of subtaxa (including subtaxa of subtaxa, etc)
n_subtaxa(x)

# Find the number of subtaxa one rank below each taxon
n_subtaxa(x, max_depth = 1)

# Only return data for some taxa (faster than subsetting the whole result)
n_subtaxa(x, subset = 1:3)
