req <- httr::GET(url)

                  type = 'text/tab-separated-values',
                  col_names = T,
                  col_types = NULL
                  )

library(TCGAbiolinks)
library(DT)
clinical <- GDCquery_clinic(project = "TCGA-STAD", type = "clinical")
datatable(clinical, filter = 'top', 
          options = list(scrollX = TRUE, keys = TRUE, pageLength = 5),  
          rownames = FALSE)
