Hello, I have the following dataset and want to calculate a P/A ratio for each replicates in the dataset. In this case, treatment 1 has 4 replicats and treatment2 has 3 replicates. The P/A = [((#of P)*2) + (# of M)]/# of replicates. The output should be two columns of P/A ratios for two treatments.
Dataset: Replicates 1 1 1 1 2 2 2 AFFX-BioB-5_at P P P P P P P AFFX-BioB-M_at P P P P P P P AFFX-BioB-3_at P P P A A P P AFFX-BioC-5_at P P P P P P P AFFX-BioC-3_at P P P P P P P AFFX-BioDn-5_at P P M P P P P AFFX-BioDn-3_at P P P P P P P AFFX-CreX-5_at P P P P P P P AFFX-CreX-3_at P P P P P P P AFFX-DapX-5_at A A P A A P A AFFX-DapX-M_at A A A A A A A AFFX-DapX-3_at A A A A A A A AFFX-LysX-5_at A A A P A A A AFFX-LysX-M_at A A A A A A A AFFX-LysX-3_at A A A A P M A AFFX-PheX-5_at A A A A A A A AFFX-PheX-M_at A A A A A A A AFFX-PheX-3_at A A A A A A A I have made this far with the following code, but have not been able to make the code work yet. Could anybody shed some light on it?
