Conflicts of GDCquery() and GDCpreapre() on the arguments of platform when downloading Illumina Methylation Epic chip data.

[LeonLiu-ZL]

When downloading methylation Epic chip data, the platform must be ""Illumina Methylation Epic v2" instead of "Illumina Methylation Epic".

query <- GDCquery(
    project = "TCGA-LUAD",
    data.category = "DNA Methylation", 
    data.type = "Methylation Beta Value",
    platform = "Illumina Methylation Epic"
)

Error in GDCquery(project = "TCGA-LUAD", data.category = "DNA Methylation", :
Please set a valid platform argument from the list below:
=> Illumina Human Methylation 450
=> Illumina Human Methylation 27
=> Illumina Methylation Epic v2

However, when "Illumina Methylation Epic v2" was used, GDCprepare() reports platform should be "Illumina Methylation Epic"

query <- GDCquery(
    project = "TCGA-LUAD",
    data.category = "DNA Methylation", 
    data.type = "Methylation Beta Value",
    platform = "Illumina Methylation Epic v2"
)
GDCdownload(query = query, directory = "./GDCdata", files.per.chunk = 10)

luad_beta <- GDCprepare(query = query, directory = "./GDCdata/")

Error in match.arg(platform) :
'arg' should be one of “Illumina Human Methylation 450”, “Illumina Human Methylation 27”, “Illumina Methylation Epic”
