A quick look at the source for the function suggests the downloading in TCGAbiolinks is done over HTTPS e.g.
>TCGAdownload
function (data = NULL, path = ".", type = NULL, samples = NULL,
force = FALSE)
{
dir.create(path, showWarnings = FALSE, recursive = TRUE)
root <- "https://tcga-data.nci.nih.gov"
.....
}
The rest of the URL is dependant upon whether you're asking for specific samples or whole datasets, but is defined in the "deployLocation" column in the data argument you pass to TGCGAdownload()
Thank you so much !
