This function selects the RNAseq data from TCGA samples, excludes
samples with label of Solid Tissue Normal and ranks the genes by their
mRNA expression.
It should not be used directly, only inside .plot_boxgraph_RNAseq_TCGA()
function.
.RNAseq_all_gene(df).TCGA_GTEX_RNAseq_sampletype_subset generated
inside .plot_boxgraph_RNAseq_TCGA()
a data frame ranking genes by their mRNA expressions in lung adenocarcinoma
Other helper function for differential expression analysis:
.RNAratio_calculation(),
.RNAratio_selection(),
.RNAratio_tumortype(),
.RNAseq_ind_gene(),
.RNAseq_tumortype()
if (FALSE) {
.RNAseq_all_gene(.TCGA_GTEX_RNAseq_sampletype_subset)
