add_line_breaks.RdThis 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.
add_line_breaks(x, n = 50, html = FALSE)Either a string or a vector; if the vector is not of class character if will be coerced to one using as.character.
Numeric: The number of characters that should separate consecutive line breaks.
Logical: Should the function add HTML line breaks (<br>)? Defaults to FALSE, in which case the newline sequence is used instead (escape-n).
Returns the input vector unaltered except for the addition of line breaks.
Line breaks are only added between words, so the value of n is acutally a threshold value rather than being matched exactly.
