cqi_id2cpos: Convert the ID of an item

Description

Associate an item's ID to other parameters.

Usage

cqi_id2cpos(attribute, id)
	cqi_id2freq(attribute, ids)
	cqi_id2str(attribute, ids)
	cqi_str2id(attribute, strs)

Arguments

attribute

(string) the qualified name of an attribute.

id

(integer) a single value

ids

(integer vector)

strs

(character vector)

Value

The cqi_id2cpos, cqi_id2freq, cqi_str2id functions return an integer. The cqi_id2str function returns a string.

Details

These functions take as argument the ID of a positional attribute item and associate corresponding parameters such as the corpus position, the frequency or the string it represents.

The cqi_str2id function does the opposite: it associates the ID to a given positional parameter.
