# Plotting Predictive Distributions of Dynamic Tree models

### Description

Plotting predictive distributions constructed from dynamic tree (regression) models for 1-d data – provided primarily for use in our 1-d examples and for illustrative purposes

### Usage

1 2 3 |

### Arguments

`x` |
a |

`add` |
a scalar |

`proj` |
when |

`ylim` |
user-specified y-axis limits values; see |

`col` |
user-specified color value; see |

`lwd` |
user-specified line-width value; see |

`ptype` |
type of plot used to visualize several predictive
samples obtained from |

`...` |
other arguments to the generic |

### Details

This plotting function only handles the predictive output from
1-dimensional regression `dynaTree`

models as obtained by
first calling `dynaTree`

and then
`predict.dynaTree`

on the resulting output at new
`XX`

locations. It is provided to help make the illustration
of our 1-d examples easier and to serve as an aid in a user's
development of custom plotting functions in higher dimensions

### Value

The only output of this function is a pretty plot
