groupedData object is summarized by the values of the
displayLevel grouping factor (or the combination of its values
and the values of the covariate indicated in preserve, if any is
present). The collapsed data is used to produce a new
groupedData object, with grouping factor given by the
displayLevel factor, which is plotted using the
appropriate plot method for groupedData objects with
single level of grouping.# S3 method for nmGroupedData

displayLevel
grouping factor, which are used to determine the panels of the
Trellis plot. If equal to TRUE, the displayLevel
element 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.
displayLevel 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.
collapseLevel grouping factor. The collapsing factor is
obtained by pasting together the levels of the collapseLevel
grouping factor and the values of the covariate to be
preserved. Default is NULL, meaning that no covariates need to
be preserved.
object that vary within the
groups defined by collapseLevel. Invariant variables are
always summarized by group using the unique value that they assume
within that group. If FUN is a single
function it will be applied to each non-invariant variable by group
to produce the summary for that variable. If FUN is a list of
functions, the names in the list should designate classes of
variables in the data such as ordered, factor, or
numeric. The indicated function will be applied to any
non-invariant variables of that class. The default functions to be
used are mean for numeric factors, and Mode for both
factor and ordered. The Mode function, defined
internally in gsummary, returns the modal or most popular
value of the variable. It is different from the mode function
that returns the S-language mode of the variable.NULL, meaning that all levels are
