taxa (version 0.2.0)

leaves: Get leaf taxa

Description

Return the leaf taxa for a taxonomy() or taxmap() object. Leaf taxa are taxa with no subtaxa.

obj$leaves(subset = NULL, value = NULL)
leaves(obj, subset = NULL, value = NULL)

Arguments

obj

The taxonomy() or taxmap() object containing taxon information to be queried.

subset

Taxon IDs, TRUE/FALSE vector, or taxon indexes to find leaves for. Default: All taxa in obj will be used. Any variable name that appears in all_names() can be used as if it was a vector on its own.

value

What data to return. This is usually the name of column in a table in obj$data. Any result of all_names(obj) can be used, but it usually only makes sense to data that corresponds to taxa 1:1, such as taxon_ranks(). By default, taxon indexes are returned.

Value

character

Examples

# NOT RUN {
# Return indexes of leaf taxa
leaves(ex_taxmap)

# Return indexes for a subset of taxa
leaves(ex_taxmap, subset = 2:17)

# Return something besides taxon indexes
leaves(ex_taxmap, value = "taxon_names")

# }
