I see this function used very often in students submission and alway wonder where it comes from. I am not a big fan of the function, since an unwary user might install many packages without explicit content when running your code. I think installing packages should require explicit user consent.

Hi nils

This function only installs if the package is needed. So no packages are installed, if not needed.

Cheers oli

Yes and that's my point. I want to decide myself if I want to install a missing package. Using require() on each library makes missing libraries very explicit.
