plot(x, outer, inner, innerGroups, xlab, ylab, strip, panel, key, ...)
x
|
an object inheriting from class nffGroupedData ,
representing a groupedData object with a factor 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 symbols, are used for each level
of the innerGroups factor. Default is NULL , meaning
that no innerGroups covariate is present.
|
xlab
|
an optional character string with the label for the
horizontal axis. Default is the y elements of attr(object,
"labels") and attr(object, "units") pasted together.
|
ylab
| an optional character string with the label for the vertical axis. Default is the grouping factor name. |
strip
|
an optional function passed as the strip argument to
the dotplot function. Default is strip.default(..., style
= 1) (see trellis.args ).
|
panel
|
an optional function used to generate the individual
panels in the Trellis display, passed as the panel argument
to the dotplot function.
|
key
|
an optional logical function or function. If TRUE
and either inner or innerGroups are non-NULL , a
legend for the different inner (innerGroups ) levels is
included at the top of the plot. If given as a function, it is passed
as the key argument to the dotplot function. Default is
TRUE is either inner or innerGroups are
non-NULL and FALSE otherwise.
|
...
|
optional arguments passed to the dotplot function.
