The goal of goi.tcga is to return a tidy tibble of TCGA expression
values from a summarizedExperiment object generated by the
TCGAbiolinks::GDCprepare()
function.
You can install goi.tcga from Github with:
devtools::install_github("koncina/goi.tcga")
library(goi.tcga)
get_tcga_goi(my_tcga_summarized_experiment, c("ACTB"))
