Python and R #1.1: Data import
In this tutorial we'll import a CSV file into both Python and R and do some introductory exploration and manipulation of the data. You will get introduced to data structures including Numpy arrays and lists in Python, and data frames and vectors in R. Although you should only actively try learning one language at a time, by being exposed to both you will get a sense of what they are each like, as well as a broader understanding of programming concepts. The first ~30 minutes of the video covers Python, and the remainder covers R.
