Building package - tab delimited example data issue

Answering to myself and staying with the same example:
        system.file("data/stroke.csv",package="ISwR")
allows direct access to the example file (name).

  

Yes, but...

This works right until you turn on LazyData for your package, then you
end up with only

00Index  Rdata.rdb  Rdata.rds  Rdata.rdx
in the data directory. 

Use the "inst" source subdir for files you want 
to have installed explicitly.

Also, in principle, it is

system.file("data", "stroke.csv", package="ISwR")


although platforms that do not understand "/" as the path separator are
rare nowadays.
