We will work with a Breast Cancer dataset from the repository The Cancer Genome Atlas. There are different subtypes of Breast Cancer. In this exercise we will compare two kinds of breast cancer subtypes.

First we will analyze the basal subtype, also called triple negative, with healthy breast tissue. You can download the normalized expression matrix and the experimental design from these links:
