A Trellis dot-plot of the response by group is generated. If outer
variables are specified, the combination of their levels are used to
determine the panels of the Trellis display. The Trellis function
dotplot is used.
# S3 method for nffGroupedData
plot(x, outer, inner, innerGroups, xlab, ylab, strip, panel, key,
grid, ...)a Trellis dot-plot of the response by group.
an object inheriting from class nffGroupedData,
representing a groupedData object with a factor primary
covariate and a single grouping level.
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.
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, "inner") 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.
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.
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.
an optional character string with the label for the vertical axis. Default is the grouping factor name.
an optional function passed as the strip argument to
the dotplot function. Default is strip.default(..., style
= 1) (see trellis.args).
an optional function used to generate the individual
panels in the Trellis display, passed as the panel argument
to the dotplot function.
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.
this argument is included for consistency with the
plot.nfnGroupedData method calling sequence. It is
ignored in this method function.
optional arguments passed to the dotplot function.
