With the advent of the Semantic Web, a huge number of Resource Description Framework (RDF) documents are being published into the Linked Open Data (LOD) Cloud. Some of these documents contain statistical data that encompasses information from various industries such as government, healthcare, schools, science, etc. Analysis of such datasets gives us valuable insights on the current socio-economic status and helps us in making decisions to improve the existing conditions. Our system offers support for executing statistical queries against RDF data. These queries are implemented as part of the SPARQL query language according to the SPARQL 1.1 specification. A library of functions is implemented, which can be added to user queries in order to incorporate statistical analysis on RDF data. Also, this library is deployed to Apache Jena Fuseki, which is a SPARQL server and accepts queries through a SPARQL endpoint. This adds to the usability of SPARQL-R library.
