pairRelation: Determine relationship between pairwise sample
In lpwgit/sampleContamination: Sample Contamination R Package

This function identifies relationship of pairwise sample [00: same patient | 10: X contaminate Y | 01 Y contaminate X | 11: both way contamination]

1 2	pairRelation(sample_pairs,center_cutoff,source_cutoff,target_cutoff, localPcomm_cutoff,region_cutoff,num_round_digit,output_path)

`sample_pairs`	data frame, pairwise samples information
`center_cutoff`	numeric, cutoff to be classified as same subject samples (default: 0.5)
`source_cutoff`	numeric, cutoff to be classififed as source sample (default: 0.4)
`target_cutoff`	numeric, cutoff to be classified as target sample (default: 0.1)
`localPcomm_cutoff`	numeric, cutoff to manage high or low SNPs sharing between a pair of samples
`region_cutoff`	numeric, cutoff for case with low SNP sharing (default: 0.75)
`num_round_digit`	integer, rounding numeric up to this decimal point (default: 3)
`output_path`	character, output directory
