subset_kinship

kinship

<p>a character vector of subject ids to identify those subjects that are shared by all inputs</p>

id2keep

<p>Since a kinship matrix has subject ids in both rownames and colnames, so we need to
remove rows and columns according to names in `id2keep`. We first remove rows and
columns of subjects that are not in `id2keep`. We then order rows and columns of the
resulting matrix by the ordering in `id2keep`.</p>

We implement an
adaptation of Jiang & Zeng's (1995) <https://www.genetics.org/content/140/3/1111> likelihood ratio test for testing
the null hypothesis of pleiotropy against the alternative hypothesis,
two separate quantitative trait loci. The test differs from that in Jiang & Zeng (1995) <https://www.genetics.org/content/140/3/1111>
and that in Tian et al. (2016) <doi:10.1534/genetics.115.183624> in
that our test accommodates multiparental populations.
