Can variables in R hold more than one data type at a time?

  • No, variables in R can hold only one data type at a time
  • None of the above
  • Yes, if the variable is a list
  • Yes, if the variable is a vector
In R, a variable can hold more than one data type at a time if it is a list. Lists in R can contain elements of different types (e.g., numbers, strings, vectors, and other lists). However, other common R data structures, such as vectors and matrices, can hold only one data type at a time.
