readREL

separate after family ID. (def=NULL, use IID only)

A PLINK REL (Relatedness) matrix is represented by<ul>
<li>.rel.bin:REL matrix in binary</li>
<li>.rel.id :FID and IID in text</li>
</ul>A binary REL matrix is the result of PLINK <code>--make-rel bin</code>

Provide function that reads binary genotype produced by 'PLINK' <https://www.cog-genomics.org/plink/1.9/input#bed> into a R matrix, or scan the genotype one variant at a time like apply(), it also provides functions that reads and writes genotype relatedness/kinship matrices created by 'PLINK' <https://www.cog-genomics.org/plink/1.9/distance#make_rel> or 'GCTA' <https://cnsgenomics.com/software/gcta/#MakingaGRM>. Currently it does not support writing back into 'PLINK' binary, it is best used for bringing data produced by 'PLINK' and 'GCTA' into R environment.
