QTLNetworkR, a R package, aims to provide a user-friendly and platform-independent tool to visualize QTL mapping results generated by QTLNetwork. It works both on the Windows, Linux/FreeBSD and MacOS platforms. The GUI is based on available add-on package RGtk2, via the aid of another package gWidgetsRGtk2. Functions for visualizing are developed by package lattice and grid that are distributed with R by default.
Because RGtk2 depends on GTK+, you may need to install GTK+ before install RGtk2. For windows user, you can do this:
download GTK+ here
Run the resulting file. This is an automated installer which will help you complete the installation of Gtk2 libraries.
For Mac OS users, you can do this:
Download GTK+ here.
Run the resulting file.
In Linux, you may or may not upgrade the GTK libraries depending on your distribution.
There are more details on RGtk2 at RGtk2’s home page.
Download R from CRAN and install it.
The following R packages are needed: RGtk2, cairoDevice, gWidgets and gWidgetsRGtk2. Install them in order, as some depend on others. All can be downloaded from CRAN.
