footnote: add footnotes to flextable

Description

The function let add footnotes to a flextable object by adding some symbols in the flextable and associated notes in the footer of the flextable.

Symbols are added to the cells designated by the selection i and j. If you use i = c(1,3) and j = c(2,5), then you will add the symbols (or the repeated symbol) to cells [1,2] and [3,5].

Usage

footnote(
  x,
  i = NULL,
  j = NULL,
  value,
  ref_symbols = NULL,
  part = "body",
  inline = FALSE,
  sep = "; "
)

Arguments

x

a flextable object

i, j

cellwise rows and columns selection

value

a call to function as_paragraph().

ref_symbols

character value, symbols to append that will be used as references to notes.

part

partname of the table (one of 'body', 'header', 'footer')

inline

whether to add footnote on same line as previous footnote or not

sep

used only when inline = TRUE, character string to use as a separator between footnotes.
