Dear colleagues,

With the help of a colleague of mine here in Helsinki (Seppo Nyrkkö) 
who looked at innards of the R source code for Mac it turned out that 
this was indeed an issue concerning the Mac locale and its settings 
and not R.

Though we had tried this earlier by changing the LANG variable to 
'fi_FI', we hadn't looked hard enough in the available encodings (with 
locale -a) to select the exactly correct value, being:

export LANG;

With this configuration R was able to happily read in my original 
table with the Scandinavian characters in the header, without no 

Thanks for your advice, and wishing all a good Midsummer,

 	-Antti Arppe
