PivotalR

PivotalR is a package that enables users of R, the most popular open source statistical programming language and environment to interact with (Greenplum) Database as well as Apache HAWQ (incubating) and the open-source database PostgreSQL for Big Data analytics. It does so by providing an interface to the operations on tables/views in the database. These operations are almost the same as those of data.frame. Minimal amount of data is transfered between R and the database system. Thus the users of R do not need to learn SQL when they operate on the objects in the database. PivotalR also lets the user to run the functions of the open-source big-data machine learning package Apache MADlib (incubating) directly from R.
