[R] Read.table for macs

[David Orlovich]

Mikkel

As mentioned earlier it's a known, (now fixed) bug.

Last night I compiled a new copy of the R-1.6.2 source with the current 
patch set installed first and it works fine under Darwin/X11 on my 
(excellent) G4/400 Mac.

I just tried reading in a dummy file and it seems to read the file 
fine.  I put mixtures of letters and numbers in the test file as this 
was reported to be a problem.  Anyway it's pasted below and it is 
exactly the same as the dummy file I typed into Excel (v. X 10.1.3).  
So ... as far as I can see the patch works.  See below.  Cheers, David 
Orlovich.
