footnote_marker_number

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, "html"))
rownames(dt)[2] <- paste0(rownames(dt)[2], footnote_marker_alphabet(1, "html"))
footnote(knitr::kable(dt, "html"), alphabet = c("Note a", "Note b"))

## End(Not run)
