R devel - Nov 2010 - .Rdata file in data subdirectory won't load

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.

Thank you for any pointers.

It needs to be polygon1.RData, not .Rdata.  You've not actually told 
us your OS, but it looks like you imagine that R is case-insensitive 
just because Windows is.

Try ?data !
