Version 0.4.7 of RKWard is now available for download.

Once again the list of new features and improvements is long. Most importantly, a large number of plugins has been added, making more R statistics features available via graphical dialogs. Many thanks to all who contributed to this release!

The changes in detail:

  • New and improved plugins:
    • t-test plugin now also allows to calculate a paired test
    • new plugin: Phillips-Perron test
    • new plugin: Mood test
    • new plugins: CLT plots for most distributions
    • new plugins: variance tests (F test (var.test), Bartlett test, Fligner test)
    • new plugin: generic plot
    • new plugin: Add grid to plot
    • new plugin: pareto chart
    • new plugin: stem-and-leaf plot
    • new plugins: outlier tests (chisq.out.test, dixon.test, grubbs.test, outlier)
    • new plugins: support of all tests from moments package
    • import SPSS and import CSV plugins gain option to open object for editing, automatically (checked by default)
    • several existing plugins have been improved in various ways
  • Bug fixes:
    • some fixes for GCC 4.3
    • fixed: the presence of user objects called "missing", "assign", or "get" would confuse some RKWard internals
    • fix a crash that occurred during startup under some circumstances
    • when flushing the output, also delete all graphs
    • make sure not to run parts of an incomplete user command. It would lead to all sorts of subtle problems
    • fixed: changing the type of a column in the data editor was broken
    • fixed: quitting while a plugin was still active would sometimes crash rkward
    • better error handling in PHP backend
    • fixed: depending on some buffer sizes, plugins could get stuck while generating code
    • fixed: plugin browser type="dir" would not work correctly
    • fixed: graph previews would stop working when the interface is switched from dialog to wizard or vice versa
  • Other user visible improvements:
    • use maximum permissible width in the object viewer
    • show current working directory in the statusbar
    • add run selection action to all HTML windows
    • add custom icons for run line/selection/all
    • if an incomplete command was piped through the console, the console does not become blocked for piping
    • make "run current line" advance the cursor to next line after running
    • warnings and errors are highlighted in command log / console (warnings only for R >= 2.5.x)
    • also support filename completion in the console (mode of completion is determined by heuristic means)
    • the currently active window is now highlighted using a thin red border
    • new shortcuts for window navigation: next/previous window, activate console, activate command log, etc.
    • make readline dialog store last size and position
    • several new help pages
    • warn when opening very large objects (with more than 250000 fields; this limit is configurable)
    • new options for plugin dialogs: Configure whether code display is shown by default, and at what size
  • Internal improvements:
    • add option to enable / disable single options of a radio or dropdown control in plugins
    • new functions rk.describe.alternative () and rk.print.literal () for use in plugins
    • in help files, a short title for sections (for the navigation bar) can be defined
    • add support for a "technical details" section in plugin help files
    • initial support for R's Sys.setlocale(), and encoding of CHARSXPs
    • plugin generated commands are run in a local() environment, allowing for more concise code
    • support R's mechanism for checking the C stack limits (only with R 2.3.x or greater, and not on all platforms)
    • add a "copy" tag to facilitate writing plugins with both dialog and wizard interfaces

We're looking forward to your feedback on the mailing list.
