Hello,
I have encountered an error accessing the data using GDCquery. The error occurs with any expression dataset.
For example, when trying to access data from TARGET-AML project using:
GDCquery(project = "TARGET-AML",
data.category = "Transcriptome Profiling",
data.type = "Gene Expression Quantification",
workflow.type = "STAR - Counts")
Hello, I have encountered an error accessing the data using GDCquery. The error occurs with any expression dataset. For example, when trying to access data from TARGET-AML project using: GDCquery(project = "TARGET-AML", data.category = "Transcriptome Profiling", data.type = "Gene Expression Quantification", workflow.type = "STAR - Counts")
I encounter the following error codes:
