So, let’s quickly start with our tutorial on R vs Python.

Difference between R and Python

R:

R language is an open source programming language. R is an integrated suite that contains various software facilities for data analysis, management and graphical analysis. It is used by data scientists to facilitate data operations on unstructured as well as structured data. It is maintained by the R core-development team – a team of volunteer developers from across the globe. Also, we use this language to perform statistical operations. And, it is available on the R-Project website www.r-project.org. R is also a command line driven program.

Python:

Python is very easy to learn language. Its feature itself is modest. They didn’t require too much time in investment. Also, its syntax is easily readable.

Moreover, Python is an ideal teaching language because of this simplicity. Thus, it also allows newcomers to pick it up quickly. Python is an excellent language for rapid prototyping. This is the main reason as to why it is becoming popular among developers. As these developers spend time in analysing the problem, Python proves to be an excellent tool that allows them to implement the solution without dwelling in the complexities of the programming language.

Advantages and Disadvantages of R and Python

Let us finally see the advantages and disadvantages of Python and R to get a clear understanding of both technologies.

Advantages of R

  • The main advantage of R is its open-source nature. You can, therefore, work with R without any licence or payment of fees. Being open-source, you can also contribute towards the customisation of R packages, newer development as well as resolution of issues. 
  • R provides exemplary support for data wrangling. The packages like dplyr, readr are capable of transforming messy data into a structured form. 
  • With over 10,000 packages in its CRAN repository, R facilitates libraries that are diverse and every field that uses data can make use of them. 
  • R has some essential features for graph plotting and aesthetic enhancement of graphs. There are popular libraries such as ggplot2 and plotly that offer a wide range of graph customisation options to the users. 
  • R is a platform independent language that can execute programs on Windows, Linux and Mac. 
  • R is a specific language that is used for statistical modeling. It is the primary tool for creating statistical tools for data science. This gives R an essential advantage over other programming languages like Python. 
  • R is constantly evolving. It provides various state of the art features that keep on updating it whenever any new algorithm is released.
  • R has an active and engaging community. There are various online forums in R that provide help and support to the R programmers. Furthermore, there are various bootcamps and online seminars that provide active education to aspiring R programmers. 

Disadvantages of R

  • The R programming language shares its roots with a much older programming language called S. Because of this, R lacks most of the features of a modern programming language like support for dynamic or 3D graphics.
  • R requires its objects to be stored in physical memory. As compared with other statistical tools, R requires more memory for its programs. Since R requires the entire data to be loaded into its memory, it is not a good option when dealing with Big Data. 
  • Since R stems from much older technology, the basic capabilities like security were not native to R. This restricts R as web applications cannot embed it or its usage as a backend computation language like Java, Python or Node.js. 
  • R poses a steep learning curve. People who had a background in statistics would find it ideal to use R. Therefore, for people who are starting afresh in data science may find R a difficult language to adapt to. 
  • Packages in R tend to be slower than other competing languages like Python and MATLAB. 
  • Most of the R algorithms are implemented on different packages. This decentralisation of packages makes it difficult to apply algorithms on problems without prior knowledge of the required package.

Advantages of Python

  • Just like R, Python is open-source. You can use Python for free. Furthermore, you can change, customise and contribute towards Python libraries.
  • Python is a general-purpose programming language that facilitates its usage over diverse tasks. Areas software development, robotics, embedded systems, automation, etc. make heavy use of python. 
  • Python comprises of state of the art APIs like tensorflow, pytorch, keras, numpy that are extremely useful in building artificial neural networks. 
  • Python is a user-friendly programming language. This is one of the main reasons as to why Python is the standard programming language in universities. 
  • Python is secure. These server-side computations involve Python as it provides various frameworks for the development of web applications. 
  • Python is apt at handling large datasets. It can load data files much faster and can also work with Big Data ecosystems. 

Disadvantages of Python

  • Being an interpreter based language, Python is slower than other languages like C, C++ and Java. 
  • Python lags behind R when it comes to statistical analysis. Python though may have improved a lot but it still lacks certain statistical packages as compared to R. 
  • The dynamically typed nature of Python makes it vulnerable to runtime errors. 
  • Python, when compared with JDBC has an underdeveloped database access layer. 
  • Tasks that require heavy memory suffer from Python. The flexible data-types in Python contribute towards its high memory consumption.
