[R] Inserting 17M entries into env took 18h, inserting 34M entries taking 5+ days

[Magnus Thor Torfason]

There are around 16M unique values. After accounting for equivalence, 
the number is much smaller (I don't know how much smaller, since my 
program has not completed yet :-)

Yes, I meant that "B and C are also equivalent". The original version 
was a typo.

Best,
Magnus
