Scatter plots of the values being compared are generated for each pair
of coefficients in
object. 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.
USAGE:
pairs(object, subset, key, ...)
REQUIRED ARGUMENTS:
object
an object of class
compareFits.
OPTIONAL ARGUMENTS:
subset
an optional logical or integer vector specifying which
rows of
object 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
(
splom or
xyplot). Defaults to
TRUE.
...
optional arguments passed down to the
trellis
function generating the plots.
VALUE:
Pairwise scatter plots of the values being compared, with different
symbols (colors) used for each object under comparison.
