Hello, I have a vector, "dates", as a series of 3 digit elements, i.e. > date [1] 528 528 528 528 528 528 528 528 528 528 528 528 708 708 708 708 708 708 [19] 708 708 708 708 529 529 529 529 529 529 529 529 529 529 529 529 529 529 [37] 529 624 I need to convert them into julian, but have to insert a "/" or "-" after the first number within each element of the vector (5/28 5/28 etc). Found plenty functions to replace by a pattern but not to cut by a certain number of digits with an element. Alternately, if I could run all the elements into one long vector and then cut every one then two digits, that would work as well.
And what about the year? You might have better luck using the Date class in R.
