[R-pkg-devel] Best practise in including third party code

[Wolfgang Lenhard]

Dear R developer list,
in general, if functionality from other packages are used in one's own 
package, it is of course the best way to declare the other package as an 
import. What is the straight forward way for only minor functions or 
functionality, especially when the other package comes with a lot 
dependencies itself? Is it advisable or ok to only use the according 
third party source code snippet and cite the other package (of course if 
the license of the package allows it; own package is AGPL, third package 
is GPL)? Or should the third party package always be installed as a 
dependency? I want to avoid bloating the installation process but it is 
very important for me not to violate academic standards, intellectual 
properties and best practise.

Thanks,
Wolfgang
