Yes, definitely.

Again, this will change with the new version.  If a new-style package
has a `data' subdirectory, its contents are installed along with the R
objects, shared libraries and help files etc.  Loading the pkg makes
these data sets available as well.

FRITZ:  When you update your pkg, please make sure that the data get
into the update as well.

Simply from the extension?  Or perhaps we could have a ``magic'' first
line telling a generic `read' what to do?  (A similar logic could be
applied to e.g. reading in xbase files using a (still unwritten) pseudo
method read.dbf which would be called if the generic read figures out
that it is looking at a dbase file (and again, using the result of
file(1) may be the better idea ...)
