I have access to controlled TCGA data but I am struggling to find the most efficient way to download and access the data in RStudio. Previously, I was able to use TCGA Biolinks to access open data. I learned from online resources that you can input an argument for your token file and use method = "client" to get access to the controlled data. However, I keep getting an error:

Error in download.file(url, ...) : cannot open URL '/system/files/public/file/gdc-client_v1.6.1_Windows_x64.zip'

and I'm not sure how to resolve it. Here is my code for what I have done up to this point:

query2_TCGA = GDCquery(
  project = "TCGA-CESC",
  data.category = "Simple Nucleotide Variation",
  experimental.strategy = "WXS",
  data.type = "Raw Simple Somatic Mutation",
  workflow.type = "VarScan2")

query2_TCGA

token = read.delim("~/tokenfile.txt")

getManifest(query2_TCGA)
GDCdownload(query = query2_TCGA,
            token.file=token,
            method = "client")

If there is a problem with my code, please let me know! Otherwise, what would you recommend for downloading and opening controlled TCGA data in RStudio? Thank you so much!

Edit: to fix the syntax for calling the token file.
