plot.compareFits            package: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.
