Dear R Experts: I am trying to convert a date and time character field to timeDate where the month is presented as three letters, such as "JUN" for June, etc. This is an example of the full character field: "04-MAY-11 1428" What is the proper format syntax? I've tried timeDate("04-MAY-11 1428",format="%d-%m-%y %H%M") but only get GMT [1] [NA] If I change the month to a number as below, then it works, but that would require recoding of the data field. timeDate("04-05-11 1428",format="%d-%m-%y %H%M") gives GMT [1] [2011-05-04 14:28:00] which is correct. How do I get R to recognize the month as a 3 letter designator. Any recommendations you can provide would be greatly appreciated.
