find_nodes: Search for nodes matching specific criteria

In anon-author/clauses: R library to help dealing with syntactic structure

Description

You can search on node attributes (lemma, pos) and on attributes of children. The function will return a data frame with the found nodes and a column for each matched child relation. The node attributes allow __i (e.g. lemma_i="bush") to match case insensitive, and __in (e.g. id__in=ids) to match multiple values. The child attributes can be either a single relation name, or a list of node attributes. The return column for children is named after the explicit rename= attribute, defaulting to the relation pattern, if given.

Usage

find_nodes(tokens, children = NULL, columns = NULL, ...)

Arguments

tokens	a df of tokens
children	a list of children, each a list of child attribute filters
columns	vector of column names to return from the node
...	node attribute filters

Value

a df with (parent) id and a column for each rel with the respective child id
