To keep the package smaller and to not install identical files (of a large size when aggregated) a second time, I aim for a minimal install. Eg no help pages. Note that the _code_ is of course there as Ra patches it.

Unfortunately, I am not likely to have enough time to polish Ra ad infinum for such aspects. I was hoping to do users like yourself (and myself) a favour by packaging it. So this is of severity "wishlist" with tag "wontfix" from my point of view. If you can cook up a small patch that sets .libPaths() to the three parts from R, I'd be happy to take it. Alternatively, we could decide that we are in favour of wasting more disk space and build the help (at least in the internal form). But I'm sure someone will then complain that the html help is missing ... Ra is not meant a replacement for R, but rather a complement which is why it has a Recommends on r-base-core. Ok?
