In qtl2pleio: Testing Pleiotropy in Multiparental Populations

Permute the phenotypes matrix and then scan the genome. Record the genomewide greatest LOD score for each permuted data set.

scan_multi_oneqtl_perm(
  probs_list,
  pheno,
  kinship_list = NULL,
  addcovar = NULL,
  n_perm = 1,
  cores = 1
)

`probs_list`	a list of founder allele probabilities, one array per chromosome
`pheno`	a matrix of trait values
`kinship_list`	a list of kinship matrices, one per chromosome
`addcovar`	a matrix of covariate values
`n_perm`	positive integer for the number of permuted data sets to scan.
`cores`	number of cores for parallelization
