This infographic is packed with good data. I especially enjoyed the section about big data startups that were acquired in 2013.
Recently I have seen blogs/articles claiming Python is the best choice for data science and R is the new language for business. Honestly, both articles are truthful and good. Both Python and R are good. Why do we have to choose? Let’s use both.
Here is my opinion. I prefer R to Python when performing exploratory data analysis. R has so many packages for every possible statistical technique. The plots, although not beautiful by default, are quick and easy to create. However, I prefer Python when I need to pull data from an API or build a software system or website. Python is more than just a statistical analysis tool; it is a complete programming language. I might even end up using Java for a project in the near future.
There does not have to be a clear winner or one single language to use. Use the best tool for the job and get on with your data science. In the end, the world cares more what you produced not whether you used R or Python or something else.
