Add line breaks to one or more strings — add_line

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.

Usage

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

Arguments

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 desired number of characters that should separate consecutive line breaks.
html: Logical: Should the line breaks be specified in html?

Value

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

Details

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

Examples

add_line_breaks(c("On the Origin of Species"), n = 10)
#> [1] "On the\nOrigin\nof\nSpecies"
