readREL

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

Reads/write binary genotype file compatible with 'PLINK' <https://www.cog-genomics.org/plink/1.9/input#bed> into/from a R matrix; traverse genotype data one windows of variants at a time, like apply() or a for loop; reads/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> into/from a R square matrix. It is best used for bringing data produced by 'PLINK' and 'GCTA' into R workflow.
