Hi, when I use "GDCprepare" function, I had a such error:

library(TCGAbiolinks)
LUAD_methy <- GDCquery(
  project = "TCGA-LUAD", 
  data.category = "DNA Methylation", 
  data.type = "Masked Intensities",
  platform = "Illumina Human Methylation 450", # Illumina Human Methylation 450
  legacy = FALSE)
GDCdownload(LUAD_methy)
GDCprepare(LUAD_methy,save = T,save.filename="LUAD_METHY_idat.Rdata")

When I run sesameDataCache(), it hasn't run for several hours. Is there a good solution? thank you

Make sure you have installed the sesame library first. then run sesameDataCache(). Catching need to be done only once per installation.
