plot.compareFits: 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 compareFits
plot(x, subset, key, mark, ...)

Value

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

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.
