Scatter plots of the values being compared are generated for each pair
of coefficients in x. Different symbols (colors) are used
for each object being compared and values corresponding to the same
group are joined by a line, to facilitate comparison of fits. If only
two coefficients are present, the trellis function
xyplot is used; otherwise the trellis function splom
is used.
# S3 method for compareFits
pairs(x, subset, key, ...)Pairwise scatter plots of the values being compared, with different symbols (colors) used for each object under comparison.
an object of class compareFits.
an optional logical or integer vector specifying which
rows of x should be used in the plots. If missing, all
rows are used.
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
(splom or xyplot). Defaults to TRUE.
optional arguments passed down to the trellis
function generating the plots.
