Arguments

x

The object.

...

Splits or SplitVector objects

lyt

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.

label

character(1). A label (not to be confused with the name) for the object/structure.

cfun

list/function/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. One of "default", "visible", "hidden". What should the display behavior be for the labels (i.e. label rows) of the children of this split. Defaults to "default" which flags the label row as visible only if the child has 0 content rows.

cformat

format spec. 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

character(1). The variable, if any, which 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

dataset (data.frame or tibble)

obj

The object.

depth

depth in tree

indent

indent

print_indent

indent for print

object

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

The new value

nested

boolean. Should this layout instruction 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

logical(1).

format

FormatSpec. Format associated with this split. Formats can be declared via strings ("xx.x") or function. In cases such as analyze calls, they can character vectors or lists of functions.

na_str

character(1). String that should be displayed when the value of x is missing. Defaults to "NA".

override

logical(1).

tt

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

incl.cont

logical. Include rows from content tables within the tree. Defaults to TRUE

add.labrows

logical. Include label rows. Defaults to FALSE

mode

character(1). 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

logical(1). Should the numbering for referential footnotes be immediately recalculated. Defaults to TRUE.

y

Second element to be rbound 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

index

j

index

drop

logical(1). Should the value in the cell 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.
