R language brca MRNA data set analysis

Let's load gene expression data .

library(RTCGA.mRNA)
?mRNA

to glance at BRCA.mRNA The size of the dataset , Show rows and columns .

dim(BRCA.mRNA)
BRCA.mRNA[1:5, 1:5]

# Take the mRNA data
BRCA.mRNA %>% 
  # then make it a tibble (nice printing while debugging)
  as_tibble() %>% 
  # then get just a few genes
  select(bcr_patient_barcode, PAX8,
