Arguments

x

(ANY)
the object.

...

splits or SplitVector objects.

lyt

(PreDataTableLayouts)
layout object pre-data used for tabulation.

spl

(Split)
the split.

pos

(numeric(1))
intended for internal use.

cmpnd_fun

(function)
intended for internal use.

constructor

(function)
constructor function.

label

(string)
a label (not to be confused with the name) for the object/structure.

cfun

(list, function, or NULL)
tabulation function(s) for creating content rows. Must accept x or df as first parameter. Must accept labelstr as the second argument. Can optionally accept all optional arguments accepted by analysis functions. See analyze().

child_labels

(string)
the display behavior for the labels (i.e. label rows) of the children of this split. Accepts "default", "visible", and "hidden". Defaults to "default" which flags the label row as visible only if the child has 0 content rows.

cformat

(string, function, or list)
format for content rows.

cna_str

(character)
NA string for use with cformat for content table.

indent_mod

(numeric)
modifier for the default indent position for the structure created by this function (subtable, content table, or row) and all of that structure's children. Defaults to 0, which corresponds to the unmodified default behavior.

cvar

(string)
the variable, if any, that the content function should accept. Defaults to NA.

extra_args

(list)
extra arguments to be passed to the tabulation function. Element position in the list corresponds to the children of this split. Named elements in the child-specific lists are ignored if they do not match a formal argument of the tabulation function.

df

(data.frame or tibble)
dataset.

obj

(ANY)
the object.

depth

(numeric(1))
depth in tree.

indent

(numeric(1))
indent.

print_indent

(numeric(1))
indent for printing.

object

(VTableTree)
a table object.

max.level

(numeric(1))
passed to utils::str. Defaults to 3 for the VTableTree method, unlike the underlying default of NA. NA is not appropriate for VTableTree objects.

value

(ANY)
the new value.

nested

(logical)
whether this layout instruction should be applied within the existing layout structure if possible (TRUE, the default) or as a new top-level element (FALSE). Ignored if it would nest a split underneath analyses, which is not allowed.

for_analyze

(flag) whether split is an analyze split.

format

(string, function, or list)
format associated with this split. Formats can be declared via strings ("xx.x") or function. In cases such as analyze calls, they can be character vectors or lists of functions. See formatters::list_valid_format_labels() for a list of all available format strings.

na_str

(string)
string that should be displayed when the value of x is missing. Defaults to "NA".

override

(flag)
whether to override attribute.

tt

(TableTree or related class)
a TableTree object representing a populated table.

incl.cont

(flag)
whether to include rows from content tables within the tree. Defaults to TRUE.

add.labrows

(flag)
whether to include label rows. Defaults to FALSE.

mode

(string)
passed on to as.vector().

rowpath

(character or NULL)
path within row structure. NULL indicates the footnote should go on the column rather than cell.

colpath

(character or NULL)
path within column structure. NULL indicates footnote should go on the row rather than cell.

reset_idx

(flag)
whether the numbering for referential footnotes should be immediately recalculated. Defaults to TRUE.

y

(ANY)
second element to be row-bound via rbind2.

path

(character)
a vector path for a position within the structure of a TableTree. Each element represents a subsequent choice amongst the children of the previous choice.

i

(numeric(1))
index.

j

(numeric(1))
index.

drop

(flag)
whether the value in the cell should be returned if one cell is selected by the combination of i and j. It is not possible to return a vector of values. To do so please consider using cell_values(). Defaults to FALSE.

Value

Various, but should be considered implementation details.
