Hi R users, I have a factor variable called date as shown below: Can anyone share the best / most efficient way to extract year and week (e.g. year = 2006, week = 52 for first record, etc..)? My data set has 1 million records. DATE 11DEC2006 11SEP2006 01APR2007 02DEC2007 Thanks in advance for any help!
