R Mode

R does not have a built-in function to calculate the mode, which is the most frequently occurring value in a dataset. However, you can create a custom function to find the mode.

Key Topics

Mode Example

# Custom function to calculate mode
get_mode <- function(values) {
    unique_values <- unique(values)
    frequency <- tabulate(match(values, unique_values))
    mode_value <- unique_values[which.max(frequency)]
    return(mode_value)
}

# Example usage
values <- c(10, 20, 20, 30, 40)
mode_value <- get_mode(values)

print(mode_value)

Output:

[1] 20

Code Explanation: The get_mode function calculates the mode by finding the most frequently occurring value in the vector values. The mode is 20 in this example.

Key Takeaways

  • R does not have a built-in mode function, but a custom function can be created.
  • The mode is the value that appears most frequently in a dataset.
  • Understanding the mode is useful for categorical and discrete data analysis.
