inpdfr
package uses RGtk2
package for its GUI. Non-linux
users may need to download additional files such as the "gtk-file" icon, or
the "hicolor" theme, which can be found by downloading GTK+ from http://www.gtk.org/.
They are not needed for the GUI to work as intended, but you may get a "GTK-WARNING"
when using loadGUI()
. Feel free to ignore this warning. The RGtk2 GUI is
not needed to access all funcionalities of inpdfr
package. Some options
are only available through the command line interface.
