word_wrap: Insert line breaks in long labels
In sjmisc: Data and Variable Transformation Functions

Description Usage Arguments Value Examples

Insert line breaks in long character strings. Useful if you want to wordwrap labels / titles for plots or tables.

1	word_wrap(labels, wrap, linesep = NULL)

`labels`	Label(s) as character string, where a line break should be inserted. Several strings may be passed as vector (see 'Examples').
`wrap`	Maximum amount of chars per line (i.e. line length). If `wrap = Inf` or `wrap = 0`, no word wrap will be performed (i.e. `labels` will be returned as is).
`linesep`	By default, this argument is `NULL` and a regular new line string (`"\n"`) is used. For HTML-purposes, for instance, `linesep` could be `"<br>"`.

New label(s) with line breaks inserted at every wrap's position.
