Head and tail methods

Usage

head(x, ...)

## S4 method for signature 'VTableTree'

  x,
  n = 6,
  ...,
  keep_topleft = TRUE,
  keep_titles = TRUE,
  keep_footers = keep_titles,
  reindex_refs = FALSE
)

tail(x, ...)

## S4 method for signature 'VTableTree'
tail(

  n = 6,
  ...,

  keep_titles = TRUE,
  keep_footers = keep_titles,
  reindex_refs = FALSE
)

Arguments

x

an object

...

arguments to be passed to or from other methods.

n

an integer vector of length up to dim(x) (or 1, for non-dimensioned objects). A logical is silently coerced to integer. Values specify the indices to be selected in the corresponding dimension (or along the length) of the object. A positive value of n[i] includes the first/last n[i] indices in that dimension, while a negative value excludes the last/first abs(n[i]), including all remaining indices. NA or non-specified values (when length(n) < length(dim(x))) select all indices in that dimension. Must contain at least one non-missing value.

keep_topleft

(flag)
if TRUE (the default), top_left material for the table will be carried over to the subset.

keep_titles

(flag)
if TRUE (the default), all title material for the table will be carried over to the subset.

keep_footers

(flag)
if TRUE, all footer material for the table will be carried over to the subset. It defaults to keep_titles.

reindex_refs

(flag)
defaults to FALSE. If TRUE, referential footnotes will be reindexed for the subset.
