Pairs Plot of compareFits Object
Usage
pairs(object, subset, key, ...)
Arguments
object
|
an object of class compareFits .
|
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.

Description
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; else the trellis
function splom
is employed.Value
Pairwise scatter plots of the values being compared, with different
symbols (colors) used for each object under comparison.Author(s)
