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.
