This is the PDF of the GenABEL tutorial, a book on how to use the GenABEL package and several other tools from the GenABEL suite (see http://www.genabel.org). It was created over the years based on course material for various lectures given by the authors. This version is based on r2005 of the SVN repository which can be found at https://r-forge.r-project.org/scm/viewvc.php/?root=genabel.
