The “all” Function in R

• Package: Base R (no specific package required)

• Purpose: Checks if all elements of a logical vector are TRUE.

• General Class: Logical Operation

• Required Argument(s):

• ...: One or more logical vectors, or objects that can be coerced to logical.

• Notable Optional Arguments:

• None

• Example:

• # Example data for using the all function
  logical_vector <- c(TRUE, TRUE, TRUE, FALSE)
  
  # Use all to check if all elements are TRUE in a logical vector
  all_result <- all(logical_vector)
  
  # Display the result
  print(all_result)

• In this example, the all function is used to check if all elements in a logical vector (logical_vector) are TRUE. The resulting logical value (all_result) is TRUE if all elements are TRUE, and FALSE otherwise. The all function is commonly used in conditions where the requirement is that all elements must be TRUE.
