I am trying to create a dba object but get this error message:

Error in [.data.frame(peaks, , 2) : undefined columns selected

This is what my sampleSheet that I made from scratch looks like

CMPdba <- dba(minOverlap=2,sampleSheet="CMP_overlapping_enhancerszeros.csv",
            config=data.frame(AnalysisMethod=DBA_DESEQ2,th= 0.05,
                      DataType=DBA_DATA_GRANGES, RunParallel=TRUE, 
                      minQCth=15, 
                      bCorPlot=FALSE, reportInit="DBA", 
                      bUsePval=TRUE),
            scoreCol= 2, skipLines=1, 
            bAddCallerConsensus=FALSE, 
            bRemoveM=TRUE, bRemoveRandom=TRUE, 
            bSummarizedExperiment=FALSE,
            attributes= "DBA_ID")

I think its a problem with what I am putting as the file path under peaks but I do not know how to fix it.
