Is there a way to split the entire genome into a genomicRanges of 2kb bins? Im thinking something along that line that uses `seqlengths()` to get chromosome length and then some function to split into 2kb bins, with a GRange for each bin. It's that 'some function' i can't seem to find. 

Take a look at ?tileGenome in the GenomicRanges package.

Cheers,
