plot.earth.models {earth} | R Documentation |

## Compare earth models by plotting them.

### Description

Compare `earth`

models by plotting them.

### Usage

```
## S3 method for class 'earth.models'
plot(x = stop("no 'x' argument"), which = c(1:2),
caption = "", jitter = 0,
col.grsq = discrete.plot.cols(length(objects)), lty.grsq = 1,
col.rsq = 0, lty.rsq = 5,
col.vline = col.grsq, lty.vline = "12",
col.npreds = 0, lty.npreds = 2,
legend.text = NULL, do.par = NULL, trace = 0,
...)
```

### Arguments

`x` |
A list of one or more |

`which` |
Which plots to plot: 1 model, 2 cumulative distribution of residuals.
Default is |

`caption` |
Overall caption. Values: |

`jitter` |
Jitter applied to GRSq and RSq values to minimize over-plotting.
Default is |

`col.grsq` |
Vector of colors for the GRSq plot.
The default is |

`lty.grsq` |
Line type for the GRSq plot.
Default is |

`col.rsq` |
Vector of colors for the RSq plot.
Default is |

`lty.rsq` |
Line type for the RSq plot.
Default is |

`col.vline` |
A vertical line is drawn for each object
to show which model size was chosen for that object.
The color of the line is |

`lty.vline` |
Line type of vertical lines (a vertical line is drawn to show the selected model for each object).
Can be a vector.
Default is |

`col.npreds` |
Vector of colors for the "number of predictors" plot within the model selection plot.
Default is |

`lty.npreds` |
Line type of the "number of predictors" plot (in the Model Selection plot).
Default is |

`legend.text` , `do.par` , `trace` |
