In migest: Methods for the Indirect Estimation of Bilateral Migration

Wrap character string to fit a target number of lines

Description

Inserts line breaks for spaces, where the position of the line breaks are chosen to provide the most balanced length of each line.

Usage

str_wrap_n(string = NULL, n = 2)

Arguments

string	Character string to be broken up
n	Number of lines to break the string over

Details

Function is intended for a small number of line breaks. The n argument is not allowed to be greater than 8 as all combinations of possible line breaks are explored.

When there a number of possible solutions that provide equally balanced number of characters in each line, the function returns the character string where the number of spaces are distributed most evenly.

Value

The original string with line breaks inserted at optimal positions.

Examples

str_wrap_n(string = "a bb ccc dddd eeee ffffff", n = 2)
str_wrap_n(string = "a bb ccc dddd eeee ffffff", n = 4)
str_wrap_n(string = "a bb ccc dddd eeee ffffff", n = 8)
str_wrap_n(string = c("a bb", "a bb ccc"), n = 2)
