We're very aware that using these internal functions ties us to a
specific version of R, and that they may change at any point in the
future and break our code. That's an acceptable trade-off - using
these internal functions gives us capabilities that makes fixing the
code in the future worthwhile.
A minimal change to R that would satisfy our needs (and I suspect
Daniel's) would be to move makeNamespace into the base package (i.e.
up out of the function it is currently contained in), and to create R
wrapper functions for registerNamespace and unregisterNamespace. They
wouldn't even need to be exported - we know what we're doing is
If that solution isn't acceptable, we'd also be very happy to work
with any R-core member to help develop a public facing API for
namespace manipulation, including providing tests for common use
Please let us know what we can do to help!
