neo2R

The aim of neo2R is to provide simple and low-level connectors for querying Neo4j graph databases. The objects returned by the query functions are either lists or data frames with minimal post-processing, allowing fast handling of queries returning many records and letting the user apply post-processing according to their data model and needs. It has been developed to support the BED package (F1000Research). Other packages such as RNeo4j or neo4R provide connectors to Neo4j databases with additional features.
