Lazy data is stored in a separate file that is loaded when

intentional that this is necessary or not. Perhaps someone else will
comment?
This is expected. The data object is not exported from the Namespace and
hence not loaded if a reference to the Namespace is made without *attaching*
the package. Hence data(..., package=...) is the way to go.
So how should I include package local data? The dataset is only used
internally by munsell functions (it's basically a big lookup table)
and should not be available to the user - i.e. it should not be
exported. This, I thought, was the purpose of sysdata.rda.

Ahhhh!!!!
Now I understand you are referring to the special name "sysdata.rda"
that is not to be loaded via data() - I thought you were talking about
the regular data including process.
That works fine for me as well and then this special data are available
when the Namespace is loaded already. Have you put that file into
package/R rather than package/data? Which R version?
