Release Notes: The default graphics device for non-interactive use is now pdf() rather than postscript(). The default width and height for pdf() and bitmap() have been changed to 7 inches to match the screen devices. Most users of the X11() device will see a new device that has different fonts, anti-aliasing of lines and fonts, and supports semi-transparent colors. Considerable efforts have been made to make the default output from graphics devices as similar as possible (and in particular close to that from postscript/pdf). There were many other enhancements.
Release Notes: Object name completion by integration of the package 'rcompletion'. A new recommended package 'codetools'. A new Rscript front end that enables shell-like R scripting.
Release Notes: This release has many new features. One important aspect is that S4 classes now have their own internal type, and S4 method dispatch has been completely revised to using cached generic functions, giving substantial performance improvements. As a consequence, all packages depending on "methods" need to be reinstalled.
Release Notes: The most important changes are probably support for UTF-8 encodings and internationalization, including (partial) translations of menus, warnings, and error messages to Chinese, German, Italian, Japanese, Portugese, and Russian.
Release Notes: Many things have changed since 1.0. The R language has acquired namespaces, exception handling constructs, formal methods and classes, much improved garbage collection, generalized I/O via connection objects, and considerable improvements in the graphics area. The user workspace has been reorganized, and so has the set of packages that ship with R. Several "recommended packages" deemed indispensable in a statistical system are bundled. In addition, there has been a large number of more specific new functions, tweaks, and bugfixes.
Release Notes: The most notable of the new features are a substantial reorganization of the standard packages, a major update of the grid package, and the fact that underscore can now be used as a regular character in variable names. Many other enhancements were also made.
Release Notes: This is a major release containing many new features, including several enhancements of the R language, a much improved version for MacOS X, name spaces for S4 classes and methods, a new standard package for maximum likelihood estimation, and rationalization of subscripting for data.frames.
Release Notes: This version features major changes to the methods/class area and uses namespaces much more widely than before. Several routines now use the faster and more modern LAPACK library. A bunch of new functions were added and an assortment of bugs were fixed.
Release Notes: Many new functions were added and bugs fixed. The recommended packages are now included in the main distribution.
Release Notes: New features in this release include improved handling of missing values in character variables, many new functions for time series analysis, improved support for S4 classes and methods, and better tools for package quality assurance..
