Details
This function does not work in Windows because the dependent package bigmemoryExtras does not support it.
In order to make lumi package still compilation under Windows, I deliberately remove the dependency of bigmemoryExtras package.
As a result, users need to manually load the bigmemoryExtras function before using this function.
The BigMatrix data files will be save in the directory file.path(saveDir, paste(savePrefix, '_bigmat', sep=”))
