[R] Reading S-plus data in R

The sdd file extension may mean that the file is in S+ 'data dump' format,
made by S+'s data.dump function and readable in S+ by its data.restore function.
foreign::data.restore can read some such files in R, but I think it
may only read well
those with using the pre-1991 format made in more recent versions of
S+ with data.dump(old.style=TRUE).
