Thanks for the explanation Mark.
If integers are being recast as doubles R is ignoring/overriding the user's
choice of data-type. There may be good reasons for doing that internally
(uniformity, code re-use etc) , but it is not what I'd expect as an end-user
--- neither ?plot nor ?xy.coords seem to mention that coordinates need to be
floating point numbers.
