R community, I am trying to create an array of the time differences between datapoints for a very large set. For some reason for 4 of the values the difference has been calculated as NA.
Looking at the individual points two of them are "1981-03-29 01:40:00" and "1981-03-29 02:00:00" This is the exact same format as the other points that return values of 20 mins as expected. In such a large dataset (600,000+ entries) I don't know why only 4 would be doing this. Apologies for such a vague question but can anyone shed any light on what may be wrong?
