Is anyone aware of a fast way of doing fisher's exact test for a series of 2
x 2 tables in R? The fisher.test is really slow if n1=1000 and n2 = 1000.
If you don't require exact two-sided p-values (determined according to a
likelihood criterion as in fisher.test), you can use the vectorised

I R 32 bit installed but my machine is 64 bit. Do I need to upgrade the R to 64

to calculate all the possible configurations and there are a lot to
calculate with the values of n1 and n2 you gave.
