Summary:
Number of genotypes is limited to (2^31-1)/4

Detailed description
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. The development team might consider to fix this problem since most machines are running 64-bit systems and R started supporting long vectors since version 3.0.
