R Comments

Comments in R are used to make code more readable and to provide explanations or notes for the programmer. Comments are ignored by the R interpreter and do not affect the code execution.

Key Topics

1. Single-Line Comments

In R, comments start with the # symbol and continue to the end of the line.

Example: Single-Line Comment

# This is a single-line comment
print("Hello, World!")

Code Explanation: The line starting with # is a comment and is ignored by R. Only the print() statement is executed.

2. Multi-Line Comments

R does not have a built-in syntax for multi-line comments. However, you can use multiple single-line comments.

Example: Multi-Line Comments

# This is a comment
# spanning multiple lines
print("Hello, World!")

Code Explanation: Each line starting with # is treated as a separate comment. This way, you can create multi-line comments.

Key Takeaways

  • Use # to add single-line comments in R.
  • R does not support multi-line comments, but you can use multiple single-line comments for the same purpose.
