\title{ Bayesian Structure Learning in Graphical Models }

\description{
The \code{R} package \pkg{BDgraph} provides statistical tools for Bayesian structure learning in undirected graphical models for continuous, count, binary, and mixed data. The package is implemented the recent improvements in the Bayesian graphical models' literature, including Mohammadi and Wit (2015), Mohammadi et al. (2017), Dobra and Mohammadi (2018), and Letac et al. (2018). The computationally intensive tasks of the package are implemented in parallel using \pkg{OpenMP} in \code{C++} and interfaced with \code{R}, to speed up the computations. Besides, the package contains several functions for simulation and visualization, as well as several multivariate datasets taken from the literature.
