Diffbind Subsetting and Plot Consensus Peakset
I am trying to plot PCA for the promoter-specific consensus peaks ( occupancy analysis) , but can't find a way to do it in DiffBind,
From this previous answer, I am able to get the promoter-specific consensus peak set but I have no idea how to compute the matrix from that peak set for the PCA :
peak.promoter <- dba.peakset(dba,bRetrieve=TRUE,
peaks=promoter.gr )
promoter.counts <- dba.count(dba,peaks=peaks)
