From ‘R vs Python’ to ‘R and Python’

In this article, you’ll learn to leverage the best of both ‘Python and R’ in a single project.

If you are into Data Science, the two programming languages that immediately come to mind are R and Python. However, instead of considering them as two options, more often than not, we end up comparing the two. R and Python, are excellent tools in their own right but are very often conceived as rivals. If you type R vs Python , in your Google search bar, you instantly get a plethora of resources on topics which talk about the supremacy of one over the other.

One of the reasons for such an outlook is because people have divided the Data Science field into camps based on the choice of the programming language they use. There is an R camp and a Python camp and history is a testimony to the fact that camps cannot live in harmony. Members of both the camps fervently believe that their choice of language is superior to the other. So, in a way, divergence doesn’t lie with the tools but with the people using those tools.

Why not use Both?

There are people in the Data Science community who are using both Python and R, but their percentage is small. On the other hand, there are a lot of people who are committed to only one programming language but wished they had access to some of the capabilities of their adversary. For instance, R users sometimes yearn for the object-oriented capacities that are native to Python and similarly, some Python users long for the wide range of the statistical distributions that are available within R.

The figure above shows the results of the survey conducted by Red Monk in the third quarter of 2018. These results are based on the popularity of the languages on Stack Overflow as well as on Github and clearly show that both R and Python are rated quite high. Therefore, there is no inherent reason as to why we cannot work with both of them on the same project. Our ultimate goal should be to do better analytics and derive better insights and choice of a programming language should not be a hindrance in achieving that.

Overview of R and Python

Let’s have a look at the various aspects of these languages and what’s good and not so good about them.

Python

Since its release in 1991, Python has been extremely popular and is widely used in data processing. Some of the reasons for its wide popularity are:

  • Object-oriented language
  • General Purpose
  • Has a lot of extensions and incredible community support
  • Simple and easy to understand and learn
  • packages like pandas, numpy and scikit-learn, make Python an excellent choice for machine learning activities.

However, Python doesn’t have specialized packages for statistical computing, unlike R.

R

R’s first release came in 1995 and since then it has gone on to become one of the most used tools for data science in the industry.

  • Object-oriented language
  • General Purpose
  • Has a lot of extensions and incredible community support
  • Simple and easy to understand and learn
  • packages like pandas, numpy and scikit-learn, make Python an excellent choice for machine learning activities.

Performance wise R is not the fastest language and can be a memory glutton sometimes when dealing with large datasets.

Leveraging the best of Both Worlds

Could we utilize the statistical prowess of R along with the programming capabilities of Python? Well, when we can easily embed SQL code within either R or Python script, why not blend R and Python together?

There are basically two approaches by which we can use both Python and R side by side in a single project.

R within Python

  • Object-oriented language
  • General Purpose
  • Has a lot of extensions and incredible community support
  • Simple and easy to understand and learn

R objects are exposed as instances of Python-implemented classes, with R functions as bound methods to those objects in a number of cases.

  • Object-oriented language
  • General Purpose
  • Has a lot of extensions and incredible community support
  • Simple and easy to understand and learn
  • packages like pandas, numpy and scikit-learn, make Python an excellent choice for machine learning activities.

rpy2 runs embedded R in a Python process. It creates a framework that can translate Python objects into R objects, pass them into R functions, and convert R output back into Python objects. rpy2 is used more often since it is one which is being actively developed.

One advantage of using R within Python is that we would able to use R’s awesome packages like ggplot2, tidyr, dplyr et al easily in Python. As an example let’s see how we can easily use ggplot2 for mapping in Python.

R vs Python: What Should Beginners Learn?

Let go of any doubts or confusion, make the right choice and then focus and thrive as a data scientist.

I currently lead a research group with data scientists who use both R and Python. I have been in this field for over 14 years. I have witnessed the growth of both languages over the years and there is now a thriving community behind both.

I did not have a straightforward journey and learned many things the hard way. However, you can avoid making the mistakes I made and lead a more focussed, more rewarding journey and reach your goals quicker than others.

Before I dive in, let’s get something out of the way. R and Python are just tools to do the same thing. Data Science. Neither of the tools is inherently better than the other. Both the tools have been evolving over years (and will likely continue to do so).

Therefore, the short answer on whether you should learn Python or R is: it depends.

The longer answer, if you can spare a few minutes, will help you focus on what really matters and avoid the most common mistakes most enthusiastic beginners aspiring to become expert data scientists make.
