[Rd] eurodist example dataset is malformed

[Jari Oksanen]

Justin,

I suggest you try to remove your malformed eurodist and use the one in R.
The svn logs show no changes in eurodist since 2005 when 'r' was added to
'Gibralta' (it still has all the wrong distances which perhaps go back to
the poor quality of Cambridge Encyclopaedia). I also installed R 2.9.1 for
MacOS to see that there neither is a change in 'eurodist' in the Mac
distribution. My virgin eurodist in Mac was clean, with all its errors. All
this hints that you have a local copy of malformed eurodist in your
computer. Perhaps

rm(eurodist)
eurodist

will help.

Cheers, Jari Oksanen
