Question

What is the mode in R?

Answer 1

In R, the mode refers to the value that occurs most frequently in a dataset. It represents the peak or the most common value in a distribution. However, unlike mean and median, the mode is not a measure of central tendency and may not exist or be unique in some datasets. In R, you can find the mode of a vector or a dataset using various functions or by implementing custom code.

Here's an example:

getMode <- function(x) {
  ux <- unique(x)
  ux[which.max(tabulate(match(x, ux)))]
}

# Example usage
data <- c(1, 2, 2, 3, 4, 4, 4, 5)
mode_value <- getMode(data)
print(mode_value)
 

Output:

[1] 4
