Hi, I am new in R and bioconductor, when using TCGAbiolinks package analysis TCGA data and performing survival analysis, I get the follwoing warning message:Is there anything I can do to solve this error? any help will be appreciated greatly!

My code is as following:

 dataSurv <- TCGAanalyze_SurvivalKM(clinical_patient = dataClin,
+                                    dataGE = dataFilt,
+                                    Genelist = rownames(dataDEGs),
+                                    Survresult = TRUE,
+                                    ThreshTop = 0.67,
+                                    ThreshDown = 0.33,
+                                    p.cut = 0.05)

Error in mRNAselected_values_ordered[1:(lastelementTOP - 1)] : 
  only 0's may be mixed with negative subscripts
