Extract arguments suitable for gplot from a data.frame with appropriate meta-data

an object of class ``data.frame'' |
display.formula |

logical or one-sided formula |

a list containing named components, to be stored as special
attributes of x , including but not limited to
These are modeled on the groupedData function in package
nlme , and are stored as meta-data in the data frame
x . The components listed above are special in the sense that
they are used by the corresponding gplotArgs method to
contruct a suitable list as descibed in
gplotArgs.default . Any other components in
value can be used to override the values thus constructed,
including display.formula .

The gplotArgs
method for data frames constructs a suitable list
as descibed in gplotArgs.default
. The
display.formula
argument can be used to specify the Trellis
formula used (usually, it will be constructed from the meta-data).
For the role of outer
and more details, consult nlme
documentation for now.
gplotArgs
should return a list.
