How long does it take to learn R programming?

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 to write loops, conditional statements, apply functions, data analysis techniques, and using the ggplot2 package to make visualizations.
  

After these concepts, you can learn how to implement statistical techniques and modeling using R.
