\title{Load data package}
\description{
 This function loads the data package, you need for seeing the demo and
 the examples. If you have already installed the data package, it will
 simply attach it via \code{library}. Otherwise it will try to download
 and install the package using functions from the package
}
\usage{
 loaddatapkg(mydatapkg,installDir=.libPaths()[1])
}
\arguments{
  \item{mydatapkg}{Name of the data package to load as String}
  \item{installDir}{Directory, into which the new package will be
		installed, if is not already installed. Defaults
		to the first entry of the standard installation
		paths.}
}
\note{The package \code{stjudem} by now is a Bioconductor example data
  package, too. Thus, you can also install it using the \code{biocLite}
  function. Try the following:
  \code{source("http://www.bioconductor.org/biocLite.R");biocLite("stjudem")}
}
