The RGtkExtra package

The RGtkExtra package provides bindings to the gtk+extra library and specifically the data-grid/sheet, icon list and directory tree widgets.


The current version is available as a GNU-zipped tar file RGtkExtra_0.1-1.tar.gz


Installation of the package requires the RGtk package. And that package must have been installed using the --clean (or -c) argument, i.e.
 R CMD INSTALL --clean RGtk
in order to create the necessary library needed by this RGtkExtra package.

Next, you will need to install the gtkextra library. (This may involve upgrading other dependent libraries.)

Given these dependencies, installing this RGtkExtra package can be as simple as



To use this package within an R session, you will need to make in <wherever>/RGtk/libs available to the dynamic loader. The simplest way to do this currently is to add this directory to your LD_LIBRARY_PATH setting as in
 setenv LD_LIBRARY_PATH  <wherever>/RGtk/libs:${LD_LIBRARY_PATH}
 export LD_LIBRARY_PATH=<wherever>/RGtk/libs:${LD_LIBRARY_PATH}

In the future, all of these issues may be taken care of automatically by R.


There is currently no version for this package for Windows available. One first needs gtkExtra working on Windows. Mail me to let me know of any interest in having it work on Windows.

    This package provides a mechanism for calling Python functions from R and vice-versa. This is used in the automated generation of the RGtk bindings between R and the C libraries of Gtk, Gnome, etc. We use the parser of the defs files provided by the pygtk interface.
