Arguments
- x
matrix of variables over which to calculate pairwise correlations
- covs
matrix of variables that serve as covariates
- covs_alt
alternate matrix of variables that serve as covariates when pairwise correlation is not complete
- ncores
number of cores over which to parallelize
Value
data.table with unweighted pairwise partial correlations
