R and Python have differences as many as simiralities. Through their comparisons, we can understand both languages better and use them effectively. I will take a look at some examples from de facto standard packages such as tidyverse and pandas for data munging tasks, and ggplot2 and matplotlib (and seaborn) for data visualisation.

1. Differences between R and Python as Language

   • Procedural and object-oriented programming
   • Specific and general purpose

2. Data Wrangling

   • tidyverse
   • pandas

3. Data Visualisation

   • ggplot2
   • matplotlib
   • plotly

4. Some Other Cases (depending on time and interest)

   • Machine learning
   • Deep learning
   • Big data (distributed data processing)
   • Natural language processing

5. Conclusion

   • To be bilingual
