Hi there, In the following code snippet, # a <- strptime("121114 0510", "%m%d%y %H%M") b <- data.frame(date = a, res = 1:5) class(a) class(b[1,1]) # I am wondering why the class of a and b[1,1] are not the same.
How to make the class of a and b[1,1] to be same? I would really appreciate you for any suggestions.
