Can I Use ComBat-Seq to adjust multigroups RNAseq?

[yirenheihei]

hi,I am confused to use the combat_seq to deal with my RNAseq data .I have two batchs and I have thress groups such as groupA vs groupB,groupA vs groupC.How I use the combat_seq?
below is my code .
group=c(rep(0,1,2),6)
batch=c(rep(0,1),9)
adjusted_counts=combat_seq(counts,batch=batch,group=group)
is this right?
thank you very much.
