Description Usage Arguments Details Value Examples

This function takes a vector of strings and adds line breaks every n characters. Primarily built to be called internally by format_citation, this function has been made available as it can be useful in other contexts.

1	add_line_breaks(x, n = 50, html = FALSE)

`x`	Either a string or a vector; if the vector is not of class `character` if will be coerced to one using `as.character`.
`n`	Numeric: The number of characters that should separate consecutive line breaks.
`html`	Logical: Should the function add HTML line breaks (`<br>`)? Defaults to FALSE, in which case the newline sequence is used instead (escape-n).

Line breaks are only added between words, so the value of n is acutally a threshold value rather than being matched exactly.

Returns the input vector unaltered except for the addition of line breaks.

file_location <- system.file(
  "extdata",
  "avian_ecology_bibliography.ris",
  package = "revtools")
x <- read_bibliography(file_location)
add_line_breaks(x$title)
