New Features

Source editor enhancements

We’ve added some new features & options to the source editor. We’ve also received lots of feedback on more advanced capabilities users want in the editor and we will definitely address this in upcoming releases. New stuff in the editor includes:

• Highlight all instances of selected text
• Insert spaces for tabs (soft-tabs)
• Customizable print margin line
• Selected line highlight
• Toggle line numbers on/off
• Optional soft-wrapping for R source files

The docs on source code editing options include more details.

Customizable layout and appearance

One of the most frequently requested features we’ve have is the ability to put the Console and Source views side-by-side. This configuration (and others) are now possible. New appearance and layout options include:

• Customize locations of panes and tabs
• Change default font size for code views
• Select from various editor themes including TextMate, Eclipse, and others.

For more details see the docs on appearance and layout options.

Interactive plotting (manipulate)

This release includes a package called manipulate that can be use to create interactive plots within RStudio. Manipulate is very flexible and includes the following capabilities:

• Generate plots with inputs bound to custom controls (rather than being hard-coded to a single value)
• Variety of control types including slider, picker, and checkbox.
• Controls appear next to the plot and can be easily shown and hidden

More details as well as screenshots with examples can be found in the manipulate documentation.

Works with R installed from source

The first beta of RStudio was compatible with the binary version of R distributed from CRAN. The current release works with any version of R, including:

• R built and installed from source using make install
• MacPorts or Homebrew versions of R on MacOS X

The docs on using different versions of R describe how RStudio determines which R to run against on each platform.

Character encoding

In this release we’ve significantly improved handling of non-ASCII characters, this includes:

• Unicode characters can be used for input and output in the console.
• The source editor supports Unicode characters and can open/save files using any character encoding.
• A product-wide default encoding can be set, and can be overridden on a per-document basis.

See the character encoding documentation for more details.

Improved management of working directories

We’ve added a number of new features to make it easier to switch between working contexts located in different directories. These include:

• Option to specify a default initial working directory
• Tools - Change Working Dir menu command to change both the working directory and Files pane.
• Optional file associations for .RData and .R that initialize RStudio within the opened file’s directory
• Windows: Startup in working directory specified for shortcuts
• Mac: Startup in folder dragged and dropped on RStudio Dock icon
• Linux: Startup in terminal working directory when run from the command line

The docs on working directories and workspaces go into more depth on these features.

Other Enhancements

Console

• Recognize \r character in console so that txtProgressBar works as expected
• Lift restrictions on size of console input which can be sent to R (was 4K total, is now 4K per line)
• Jump to next non-blank line in source after executing via Ctrl-Enter

Source Editing

• Improved size and legibility of default fonts on Windows & Linux

• New keyboard shortcuts:

  • Alt- for inserting assignment (“<-") operator.
  • Ctrl+Shift+Home/End for select to start/end
