Hi all, I was trying to perform differential expression analysis of TCGA data with TCGAbiolinks bioconducter package in R where we have to normalize the data and filter. I am getting the following error in the normalization step. Can anyone resolve it?

dataNorm_normal <- TCGAanalyze_Normalization(tabDF = 'data', geneInfo)

Error in array(x, c(length(x), 1L), if (!is.null(names(x))) list(names(x), : 'data' must be of a vector type, was 'NULL'

Data was downloaded and prepared using TCGAbiolinks and it is present in a current working directory

Thanks in advance
