Convert a quanteda dictionary to keywords

Description

This function converts or reads a dictionary object from quanteda to a named list. "Glob"-style wildcard expressions (e.g. politic*) are resolved based on the available terms in your texts.

Usage

read_keywords(file = NULL, docs = NULL, dictionary = NULL, split = TRUE, ...)

Arguments

file	file identifier for a foreign dictionary, e.g. path to a dictionary in YAML or LIWC format
docs	texts read via keyATM_read()
dictionary	a quanteda dictionary object, ignore if file is not NULL
split	boolean, if multi-word terms be seperated, e.g. "air force" splits into "air" and "force".
...	additional parameters for quanteda::dictionary()

Value

a named list which can be used as keywords for e.g. keyATM()
