I have three sets of multiple samples to compare. Those are basically the sequences of three samples and I need to compare them letter by letter (DNA sequences) and I was wondering if there is anyway I can show some concordance using any statistical methods or any codes/package in R. I don't have good knowledge of statistics and would really appreciate if any one can help me explain how to compare them.
Say I have three samples, sampleA, SampleB and SampleC. I want to compare the sequence concordance with the sets of each two and then all three samples (overall concordance). I just want to get the statistical significance for their concordance.
sampleA: AATGCCTGGAAA sampleB: AATGCTTGGAAA sampleC: TTTGCCTGG
