The “cut” Function in R

• Package: Base R (no specific package required)

• Purpose: Divides a numeric vector into intervals (bins) and labels each interval.

• General Class: Data Manipulation

• Required Argument(s):

• x: A numeric vector or an object that can be coerced to numeric.

• breaks: Either a numeric vector of two or more unique cut points or a single number specifying the number of intervals into which x is to be cut.

• Notable Optional Arguments:

• labels: Labels for the resulting levels of the factor.

• include.lowest: A logical value indicating if the intervals should be left-closed.

• right: A logical value indicating if the intervals should be right-closed.

• dig.lab: An integer specifying the number of digits to round labels.

• Example:

• # Example data for using the cut function
  values <- c(10, 25, 15, 35, 40, 5, 30)
  
  # Cut the numeric vector into intervals
  cut_intervals <- cut(values, breaks = c(0, 10, 20, 30, 40), labels = c("A", "B", "C", "D"))
  
  # Display the result
  print(cut_intervals)

• In this example, the cut function from base R is used to cut a numeric vector (values) into intervals defined by the specified breaks. The resulting object (cut_intervals) is a factor with labels assigned to each interval.
