grepreaper (version 0.1.0)

Efficient Data Filtering and Aggregation Using Grep

Description

Provides an interface to the system-level 'grep' utility for efficiently reading, filtering, and aggregating data from multiple flat files. By pre-filtering data at the command line before it enters the R environment, the package reduces memory overhead and improves ingestion speed. Includes functions for counting records across large file systems and supports recursive directory searching.
