Subject: [Rd] sysdata.rda, namespaces and package dependencies
Message-ID: <CABdHhvHJCstQrsoCWhMTys6Jba5egWO6iprm2TuFy0Zrb==U1Q@mail.gmail.com>

Hi all,

I'm struggling with accessing a package dataset (munsell.map, stored
in sysdata.rda) when that package is imported, not required.  A simple
reproducible example is:

install.packages("munsell")
munsell::mnsl("10B 4/6")
# Error in match(col, munsell.map$name) : object 'munsell.map' not found

library(munsell)
munsell::mnsl("10B 4/6")
# Function works correctly

Am I doing something wrong, or is this namespace bug?
