PB-Shinde commented 2 years ago

I am following the tutorial on https://statomics.github.io/PDA21/cptac_robust.html this link, but when i reach this command to check for non zero intensities

rowData(pe[["peptideRaw"]])$nNonZero <- rowSums(assay(pe[["peptideRaw"]]) > 0)

it raised the error about x should be array of atleast two dimensions

so checked the data inside table by

pe[["peptideRaw"]] NULL

resulting in null, i am using exact copy paste command from tutorial. please help
