`obj` |
A |

`x` |
A |

`what` |
Character indicating what parameters to plot.
Possible values are |

`scales` |
Character vector of length two, with possible values "same" or
"free", indicating whether x- and y-axes of the plots should be
constrained to be the same across panels. For |

`layout` |
Character. If |

`aspect` |
How should the panels be scaled. Default ( |

`check` |
Logical. Should the density plots be separate for each chain (in order to check convergence) or should the chains be merged. |

`lwd` |
Width of the lines used for plotting of the posterior densities. |

`col` |
Color of the lines points used for plotting of the posterior densities. |

`plot.points` |
Logical. Should a rug with actual data points be plotted beneath the density. |

`pch` |
Plot symbol for the points. |

`subset` |
Character or numerical indicating the columns of the posterior
that should be plotted by |

`cex` |
Plot character size for points in |

`...` |
Further aruments passed on to the |

A `Lattice`

plot is returned, which means that it must
`print`

ed when these functions are called in a batch program or
inside another function or for-loop.

`trace`

plots traces of the sampled chains,
`post`

plots posterior densities of the parameters and
`pairs`

plots a scatter-plot matrix of bivariate marginal
posterior distributions.

A `Lattice`

plot.
