ABSTRACT
As the name implies, the RGtk2 package is an interface, or binding, between R and GTK+, a mature, cross-platform GUI toolkit. The letters GTK stand for the GIMP ToolKit, with the word GIMP recording the origin of the library as part of the GNU Image Manipulation Program. GTK+ provides the same widgets on every platform, though it can be customized to emulate platform-specific look and feel. The library is written in C, which facilitates access from languages like R that are also implemented in C. GTK+ is licensed under the Lesser GNU Public License (LGPL), while RGtk2 is under the GNU Public License (GPL). The package is available from the Comprehensive R Archive Network (CRAN) at https://CRAN.R-project.org/package=RGtk2 .
