How is the range function used in the R language?

There is no built-in function called range in R language, but you can use the range function to calculate the range of a set of values. You can define a range function as follows:

range <- function(x) {
  min_value <- min(x)
  max_value <- max(x)
  range_value <- max_value - min_value
  return(range_value)
}

This custom range function takes a numeric vector as input and returns the range of that vector. The range is defined as the difference between the maximum and minimum values in the vector. For example, for a vector x = c(3, 1, 5, 2, 4), using range(x) will return 4, because the maximum value is 5, the minimum value is 1, and the range is 5-1=4.

Please note that there is also a built-in function called range in R language, which can return the minimum and maximum values of a numeric vector. For example, using range(x) will return a vector containing the minimum and maximum values, such as c(1, 5).
