[GenABEL-dev] [genabel-Bugs][5118] Number of genotypes is limited to (2^31-1)/4

[Yury Aulchenko]

Interesting. I thought the fact that R>3.0 allows for very long vectors "automatically" fixes the bug reported below.

> The current GenABEL can only handle (2^31-1)*4 genotypes, corresponding approximately less than 4.3 million SNPs in 2,000 samples. The problem is caused by the upper limit of vector length 2^31-1 in R/GenABEL. A lot of functions in GenABEL are influenced by this limitation.
