If you are using open-source tools, you can bring your own driver or use community packages вЂ“ many open-source drivers and community packages exist for connecting to a variety of databases. The examples below use the Oracle ODBC driver. If you are using RStudio Desktop Pro or other RStudio professional products, you can download RStudio Professional Drivers for no additional cost on the same machine where these products are installed. These new features are extensible and will work with any R package that has a connections contract. The IDE has a wizard for setting up new connections, and a tab for exploring established connections. With the latest versions of the RStudio IDE, you can connect to, explore, and view data in a variety of databases. RStudio also made recent improvements to its products so they work better with databases. The odbc R package is DBI-compliant, and is recommended for ODBC connections. The odbc R package provides a standard way for you to connect to any database as long as you have an ODBC driver installed. As of this writing, SQL variants are supported for the following databases: Oracle, Microsoft SQL Server, PostgreSQL, Amazon Redshift, Apache Hive, and Apache Impala. The dplyr package now has a generalized SQL backend for talking to databases, and the new dbplyr package translates R code into database-specific variants. When working with databases, you should always use packages that are DBI-compliant. The DBI specification has gone through many recent improvements.

The query examples below demonstrate some of the capabilities of these R packages. Several recent package improvements make it easier for you to use databases with R.
