[Rd] Snippets from other packages/ License

[Felix Schönbrodt]

Hello,

I want to use a function from another package (which is GPL>=3), about 20 lines of code, in my own package.
I somewhat hesitate to depend on the entire package just for this single function, but of course I want to credit the original authors.

What would be the best way to do that? Where should I put that credit? Or should I proceed completely different?

Best,
Felix
