Deleted:Define the group of sample in DESeq2

Question

[microorganism_001]

Sorry, sir pardon me I'm deleting this post due to put my own work in public platform. I get the result also in DESeq2 for Differential gene expression with this command but I can not define a class of sample in the script could anyone write the DESeq2 code? For reference, I want to say I have 9 samples 3 for each ( A1, A2, A3, B1, B2, B3, C1, C2, C3) I want to get differentially genes between A and C sample. Thanks!

dds <- DESeq(DESeq.md)
