Usage
get_children(taxlist, ...)
# S3 method for taxlist
get_children(taxlist, ConceptID, ...)
get_parents(taxlist, ...)
# S3 method for taxlist
get_parents(taxlist, ConceptID, ...)Arguments
- taxlist
A taxlist object.
- ...
Further arguments passed among methods.
- ConceptID
Concept IDs for selecting parents or children or a subset of
taxlist.
Value
A taxlist object with a subset including requested concepts with children or parents.
Details
This function produces subsets of taxlist objects
including all children or parents of queried taxon concepts.
Multiple concepts can be queried in these function.
The argument ConceptID can be a vector of concept IDs or a subset of
the input taxlist object.
