Vignettes code chunks style

[TobiasB22]

Do we want to enhance the style of the Intro2bipartite vignette?

For example by using the LaTeX listings-package to highlight the code chunks?

I also already kind of fixed the issue of overflowing code outputs by adding options(width = 80) and options(str = strOptions(strict.width = "cut")) to the beginning of the document.

Additionally, it would probably be nice to wrap up long code lines for readability.

Whatever floats your boat.
The current style is not particularly nice, but it clearly indicates "hello, this is code". I do like the listing package, but its R-style is rather bland.
