elasticsearchr – a Lightweight Elasticsearch Client for R

Elasticsearch is a distributed NoSQL document store search-engine and column-oriented database, whose fast (near real-time) reads and powerful aggregation engine make it an excellent choice as an'analytics database' for R&D, production-use or both. Installation is simple, it ships with sensible default settings that allow it to work effectively out-of-the-box, and all interaction is made via a set of intuitive and extremely well documented RESTful APIs. I've been using it for two years now and I am evangelical. The elasticsearchr package implements a simple Domain-Specific Language (DSL) for indexing, deleting, querying, sorting and aggregating data in Elasticsearch, from within R. The main purpose of this package is to remove the labour involved with assembling HTTP requests to Elasticsearch's REST APIs and processing the responses. Instead, users of this package need only send and receive data frames to Elasticsearch resources.
