We’re pleased to announce that the final version of RStudio v0.98 is available for download now. Highlights of the new release include:

There are also lots of smaller improvements and bug fixes across the product, check out the release notes for full details.

Debugging Tools

The feature we’re most excited about is the addition of a full interactive debugger to the IDE. Noteworthy capabilities of the debugger include:

Here’s a screenshot of the IDE after hitting an editor breakpoint:


For more details on how to take advantage of the new debugging tools, see Debugging with RStudio.

Environment Pane

The Workspace pane is now called the Environment pane and has numerous improvements, including:

R Presentations

R Presentations enable easy authoring of HTML5 presentations. R Presentations are based on R Markdown, and include the following features:

Here’s a screenshot showing a simple presentation being authored and previewed within the IDE:


For more details see the documentation on Authoring R Presentations.

Viewer Pane

RStudio now includes a Viewer pane that can be used to view local web content. This includes both static web content or even a local web application created using Shiny, Rook, or OpenCPU. This is especially useful for packages that have R bindings to Javascript data visualization libraries.

The googleVis and rCharts packages have already been updated to take advantage of the Viewer pane. Here’s a screenshot of the googleVis integration:


We’re hopeful that there will be many more compelling uses of the Viewer. For more details see the article Extending RStudio with the Viewer Pane.

Shiny Integration

We’ve added a number of features to support development of Shiny web applications, including:

Mac UI Framework

In RStudio v0.98 we also migrated our Mac WebKit engine from a cross-platform framework (Qt) to Cocoa. The original motivation for this was compatibility problems between Qt and OS X Mavericks, but as it turned out the move to Cocoa WebKit yielded substantially faster editor, scrolling, layout, and graphics performance across the board. If you are a Mac user you’ll find everything about the product snappier in v0.98.

In the next major version of RStudio we’re hoping to make comparable improvements in performance on both Linux and Windows by using a more modern WebKit on those platforms as well.

RStudio Server Professional Edition

Over the years we’ve gotten lots of feedback from larger organizations deploying RStudio Server on the features they’d like to see for production deployments of the server. With RStudio v0.98 we’re introducing a new Professional Edition of RStudio Server that incorporates much of this feedback. Highlights include:

The RStudio Server product page has full details on the Professional Edition, and an evaluation version of the server is also available for download.

New Support Site

With this release we’re also introducing a brand new support and documentation website, please visit us there with questions, feedback, as well as what other improvements you’d like to see in the product.
