[R] Loading Rdata files in a Package

[Prof Brian Ripley]

>From ?data

        2. files ending ‘.RData’ or ‘.rda’ are ‘load()’ed.

'.Rdata' (l/c 'd') files are not supported (although on 
case-insensitive file systems they will work in _some_ circumstances, 
but only some. Without the sessionInfo() output we asked for in the 
posting guide, we can only guess if this such a file system.).
