The “max” Function in R

• Package: Base R (no specific package required)

• Purpose: Calculates the maximum value in a numeric vector.

• General Class: Descriptive Statistics

• Required Argument(s):

• ...: Numeric vectors.

• Notable Optional Arguments:

• na.rm: A logical value indicating whether NA values should be stripped before the computation proceeds. The default is FALSE.

• Example:

• # Example vectors
  data1 <- c(2, 4, 6, 8, 10)
  data2 <- c(3, 1, 7, 5, 9, NA)
  
  # Calculate maximum value
  result1 <- max(data1)
  print(result1)
  
  # Calculate maximum value excluding NA values
  result2 <- max(data2, na.rm = TRUE)
  print(result2)

• In this example, the max function calculates the maximum value in two numeric vectors (data1 and data2). The first call doesn’t include the na.rm argument, and the second call includes na.rm = TRUE to exclude NA values from the calculation. The results are then printed to the console.
