[R] LCG with modulo 2^30

[Enayetur Raheem]

I can't run a function which generates random numbrers using linear 
congruential generator. My multiplier is a=5+8^6, increment is b=1 and 
modulo is m=2^30.

the code I have written works for modulo upto  m=2^28.

For m= 2^29 , it says, can not allocate memory for the vector or something 
like that.
For m= 2^31 or more, its says the argument  "for i in 1:m "  is too large in 
magnitude.

I tried to increase the memory size but it did not  work.

Any help will be appreciated.

Thanks.
