The next version of RStudio has entered preview, with improvements including a terminal tab, and more flexible API.

Other improvements in R Studio v1.1.331 include easier connections to databases, and an object explorer. RStudio is an integrated development environment (IDE) for R and includes a code console, syntax-highlighting editor, and tools for plotting, history, debugging and workspace management.

The improvements to database connections are via the new Connections tab that can also be used to explore databases and view data in a number of database formats, including any ODBC data source, Spark, and the ability to integrate with other R packages. Connections you make are saved and can be used to connect again more easily.

Another new tab in the studio is the Terminal tab. This provides access to the system shell within the RStudio IDE. Suggested uses include source-control operations, execution of long-running jobs, remote logins, and interactive full-screen terminal applications such as text editors and terminal multiplexers.

 The object explorer has new features to help it explore hierarchical or deeply-nested R objects. It can recursively inspect R lists, environments, functions, S4 objects, and can generate R code that can be used to access a particular item within object. It is also integratedwith the xml2 package for exploration of XML documents.

The RStudio API has also been improved, making it easier to work with RStudio add-ins and packages. The Server Pro version has added support for floating (lease-based) licenses, as well as the ability to use user-defined session labels. and user-initiated session quit and force-terminate. It has also added support for admin-supplied notifications in R sessions. Elsewhere, there are improvements to Data Import, R Markdown, R Notebooks, and Git integration.
