plot(x, outer, inner, innerGroups, xlab, ylab, strip, aspect, panel, key, grid, ...)
x
|
an object inheriting from class nfnGroupedData ,
representing a groupedData object with a numeric primary
covariate and a single grouping level.
|
outer
|
an optional logical value or one-sided formula,
indicating covariates that are outer to the grouping factor, which
are used to determine the panels of the Trellis plot. If
equal to TRUE , attr(object, "outer") is used to
indicate the outer covariates. An outer covariate is invariant within
the sets of rows defined by the grouping factor. Ordering of the
groups is done in such a way as to preserve adjacency of groups with
the same value of the outer variables. Defaults to NULL ,
meaning that no outer covariates are to be used.
|
inner
|
an optional logical value or one-sided formula, indicating
a covariate that is inner to the grouping factor, which is used to
associate points within each panel of the Trellis plot. If
equal to TRUE , attr(object, "outer") is used to
indicate the inner covariate. An inner covariate can change within
the sets of rows defined by the grouping factor. Defaults to
NULL , meaning that no inner covariate is present.
|
innerGroups
|
an optional one-sided formula specifying a factor
to be used for grouping the levels of the inner
covariate. Different colors, or line types, are used for each level
of the innerGroups factor. Default is NULL , meaning
that no innerGroups covariate is present.
|
xlab, ylab
|
optional character strings with the labels for the
plot. Default is the corresponding elements of attr(object,
"labels") and attr(object, "units") pasted together.
|
strip
|
an optional function passed as the strip argument to
the xyplot function. Default is strip.default(..., style
= 1) (see trellis.args ).
|
aspect
|
an optional character string indicating the aspect ratio
for the plot passed as the aspect argument to the
xyplot function. Default is "xy" (see
trellis.args ).
|
panel
|
an optional function used to generate the individual
panels in the Trellis display, passed as the panel argument
to the xyplot function.
|
key
|
an optional logical function or function. If TRUE
and innerGroups is non-NULL , a legend for the
different innerGroups levels is included at the top of the
plot. If given as a function, it is passed as the key argument
to the xyplot function. Default is TRUE if
innerGroups is non-NULL and FALSE otherwise.
|
grid
|
an optional logical value indicating whether a grid should
be added to plot. Default is TRUE .
|
...
|
optional arguments passed to the xyplot function.
