In your raw dataset there is a variable (column) called 'Date' and it has values of the following format: "2017-08-27 20:45:20 EDT". Select the most appropriate description. Answer choices Select an option That variable should be split into two separate variables, 'Date' and 'Time' using the 'split string' operation as described in Hadley Wickham's paper. The variable name is misleading and should be changed to 'Date/Time'. That variable should be split into two separate variables, 'Date' and 'Time' using the 'melt' operation as described in Hadley Wickham's paper. Such variables are commonplace in datasets and perfectly acceptable for analysis. No action should be taken
