GTK on Windows

msGUI's graphical interface requires the GTK+ graphical libraries and a few R packages that allow R to use these libraries. If you use GTK-based software, such as GIMP, the components will already be installed on your system and you can jump straight to step 3. If you don't have GTK+ or are unsure, proceed to step 1.

1. Download the latest GTK libraries from http://gtk-win.sourceforge.net/home/index.php/Main/Downloads. The file you need is called gtk2-runtime- version - some recent date -ash.exe.

2. Run the downloaded file to install the libraries.

3. Now for the R part. Open R and run install.packages("gWidgetsRGtk2", dep = TRUE). This should install all required dependencies in one go (requires proper writing permissions).

   In case the one liner fails, RGtk2, cairoDevice, gWidgets, and gWidgetsRGtk2 can be installed on by one in this specific order.
