plot.compareFits {nlme} | R Documentation |

## Plot a compareFits Object

### Description

A Trellis `dotplot`

of the values being compared, with different
rows per group, is generated, with a different panel for each
coefficient. Different symbols (colors) are used for each object being
compared.

### Usage

## S3 method for class 'compareFits':
plot(x, subset, key, mark, ...)

### Arguments

`x` |
an object of class `compareFits` . |

`subset` |
an optional logical or integer vector specifying which
rows of `x` should be used in the plots. If missing, all
rows are used. |

`key` |
an optional logical value, or list. If `TRUE` , a legend
is included at the top of the plot indicating which symbols (colors)
correspond to which objects being compared. If `FALSE` , no legend
is included. If given as a list, `key` is passed down as an
argument to the `trellis` function generating the plots
(`dotplot` ). Defaults to `TRUE` . |

`mark` |
an optional numeric vector, of length equal to the number of
coefficients being compared, indicating where vertical lines should
be drawn in the plots. If missing, no lines are drawn. |

`...` |
optional arguments passed down to the `trellis`
function generating the plots. |

### Value

A Trellis `dotplot`

of the values being compared, with rows
determined by the groups and panels by the coefficients.
