footnote_marker_number: Footnote marker

In kableExtra: Construct Complex Table with 'kable' and Pipe Syntax

Footnote marker

Description

Put footnote mark in superscription in table. Unless you are using it in the caption of kable, you will need to put escape = F in kable (similar with cell_spec). Again, similar with cell_spec, the format option here can read default value from global option knitr.table.format.

Usage

footnote_marker_number(x, format, double_escape = FALSE)

footnote_marker_alphabet(x, format, double_escape = FALSE)

footnote_marker_symbol(x, format, double_escape = FALSE)

Arguments

x	a number. For example, for footnote_marker_alphabet(2) will return "b" in HTML.
format	Either html or latex. All functions here can read default value from global option knitr.table.format.
double_escape	T/F if output is in LaTeX, whether it should be double escaped. If you are using footnote_marker in ⁠group_rows`` labeling row or ⁠add_header_above⁠, you need to set this to be ⁠TRUE'.

Examples

## Not run: 
dt <- mtcars[1:5, 1:5]
colnames(dt)[1] <- paste0("mpg",
                          footnote_marker_alphabet(2))
rownames(dt)[2] <- paste0(rownames(dt)[2],
                          footnote_marker_alphabet(1))
dt[1,2] <- paste0(dt[1,2], footnote_marker_alphabet(3))

kbl(dt, escape = FALSE) |>
  footnote(alphabet = c("Note a", "Note b", "Note c"))

## End(Not run)
