Materialize Lazy Mappings

Description

The function tmMap supports so-called lazy mappings, that are mappings which are delayed until the documents' content is accessed. This function triggers the evaluation, i.e., it materializes the documents.

Usage

materialize(corpus, range = seq_along(corpus))

Arguments

corpus A document collection with lazy mappings.
range The indices of documents to be materialized.

Value

A corpus with materialized, i.e., all mappings computed and applied, documents for the requested range.
