Source: R/ctwas_region_cor.R

It loads precomputed correlation matrices for a single region. It could load correlation matrices by region_id and directory of correlation matrices cor_dir. Otherwise, it loads correlation matrices by the filenames (R_sg_file, R_sg_file, R_s_file) if they are provided.
