`beta` |
A matrix of model coefficients. Each row represents an MCMC draw. Each column represents a coefficient for a variable. |

`burn` |
The number of MCMC iterations in the ojbect to be discarded as burn-in. |

`inclusion.threshold` |
Only plot coefficients with posterior inclusion probabilities exceeding this value. |

`scale.factors` |
If non-null then a vector of scale factors with which to
scale the columns of beta. A |

`number.of.variables` |
If non- |

`...` |
Additional arguments to be passed to |

Returns the value from the final call to `boxplot`
