Re: [Rd] sysdata.rda, namespaces and package dependencies

I struggled with this for a while too, and I have no idea why this data object is unavailable. Finally I found this can do the trick:

data(munsell_map, package = "munsell")
munsell::mnsl("10B 4/6")
## works

But I still cannot understand this.

Regards,
Yihui
