R vs python – programming languages

Several Big Data Visualization tools have been evaluated in this weeks paper.  While the focus was primarily on R and Python with GUI tools, new tools are being introduced every day.  Compare and contrast the use of R vs Python and identify the pros and cons of each. Provide an example of both programming languages with coding examples as well as your experience in using one or both programming languages in professional or personal work. If you have no experience with either language, please discuss how you foresee using either/both of these languages in visualizing data when analyzing big data.
