Subject: [Rd] .Rdata file in data subdirectory won't load
Message-ID: <AANLkTinN+tVh7XJtqpc521TjEnMPzxxkHaT-BWLCgrJ+@mail.gmail.com>

Greetings,
  I wanted to add a dataset to a complete R package I am working on
(the package cleanly installs and passes the R CMD check).
The data (a matrix) was saved, and the save() image dragged to the
/data folder, and is a .Rdata file.  It can be read directly using
load (see below), but now the R CMD check indicates "subdirectory data
contains no datasets" and it won't load using 'data()'.  I have read
through the R extensions manual and Leisch's tutorial, but can't find
a good hint as to what is going wrong.  I also tried this with
'polygon1'
added to the 'export' in the NAMESPACE, with no effect.

> library(latticeDensity)
> data(polygon1)

Thank you for any pointers.
