TCGAretriever (version 1.3)

get_protein_data: Retrieve Protein Expression Data from a TCGA Study

Description

TCGA includes Information about Protein Expression measured by reverse-phase protein arrays. Antibody Information can be exported together with Expression Data. All expression data will be retrieved for all available protein targets.

Usage

get_protein_data(case_id = NULL, array_info = TRUE)

Arguments

case_id

String corresponding to the Identifier of the Case List of Interest

array_info

Logical. If TRUE, Antibody Information will also be exported

Value

Data Frame with one gene (protein target) per row
