NAMESPACES for data only packages
3 messages · Michael Friendly, Joshua Wiley, Brian Ripley
Hi Michael,
You are correct that data does not *have* to be exported. For
example, here is the contents of NAMESPACE for the datasets package
from a recent devel version:
# This package exports nothing (it uses lazydata)
# exportPattern(".")
Cheers,
Josh

Can we clarify: As the NEWS says, to install a data-only package under 2.14.0 you need a namespace. And if you do not give one installation will create one. However, you can use an already-installed data-only package without a namespace under 2.14.x, but not under R-devel. This is to allow a transition (e.g. many of the BioC 2.9 binary data-only packages did not have a namespace at the time).
