If you have experience in any programming language, it takes 7 days to learn R programming spending at least 3 hours a day. If you are a beginner, it takes 3 weeks to learn R programming.
- In the first week, learn about R basics like data types, operators, variables, and basic functions
- In the second week, learn concepts like how to create, append, subset datasets, lists, join.
- In the third week, learn writing loops, conditional statements, apply functions, data analysis techniques, and using ggplot2 package to make visualizations.
- After these concepts, you can learn how to implement statistical techniques and modeling using R.
