If an R package's licence X is, do all the content in that package have to be licenced under X? [closed]

Question

Hope the question above is clear.

Now my case: For my package, i'm using several libraries (jars). Each library has been licenced under one of these: Apache v2, BSD or LPGL.

Edit [some clarification] I have my own java classes packed in a jar. These import classes (dynamic linking) from the libraries mentioned here [End Edit]

Question 1: Can i pack all these libraries in a single package?
Question 1a: If yes, under what licence Apache, BSD, LGPL or any other?
Question 1b: If yes, would it be enough to put all the library names in a NOTICE and to write under what licence is a library licenced together?

Question 2: Or do i have to create for each type of licence a separate package and put libraries in it according to their licence type?

Answer 1

You can't use a single license for your package. Instead, in your DESCRIPTION put "License: file LICENSE" and describe the individual licenses in that file.

Answer 2

R itself is licensed under the GPL. It contains other functionality released under different licences, such a PCRE which is licensed under BSD. The R sources contain separate licence files for the different components as well as copyright statements/acknowledgements.

Edit [some clarification] So in and of itself, if you are redistributing libraries as part of your package you need to preserve their licence details and respect the licence under which they were distributed. Your package can have whatever licence you want as long as it is not in conflict with the licences of the libraries you are redistributing (unlikely given the ones you cite). You make clear what licence your package is under in the DESCRIPTION file (as Hadley mentions in his answer), but you should make sure a LICENCE, or COPYING file is included in the top level of the package source so it is clear what code is under what licence etc. [End edit]

The problem you are going to have is that unless we have some lawyers hereabouts who are coders, any advice given should be taken with a big pinch of salt. If you are worried about this, you should seek expert advice.
