Hi,

Is there any problem with them ?

tcga_id <- "TCGA-HNSC"

query <- GDCquery(
  project = tcga_id,
  data.category = "Transcriptome Profiling", 
  data.type = "Gene Expression Quantification",
  experimental.strategy = "RNA-Seq",
  sample.type = c("Primary Tumor", "Metastatic", "Recurrent Tumor"), 
  access = "open",  # files open source,
  workflow.type = "STAR - Counts"
)
