I'm currently working in tick data with R and I would like to merge date and time into a single object as I need to get a precise time object to compute some statistics on my data. Here is how my data looks like:
date time price flag exchange
2 XXH10 2010-02-02 08:00:03 2787 1824 E
3 XXH10 2010-02-02 08:00:04 2786 3 E
4 XXH10 2010-02-02 08:00:04 2787 6 E
5 XXH10 2010-02-02 08:00:04 2787 1 E
6 XXH10 2010-02-02 08:00:04 2787 1 E
Basically, I would like to merge the columns "date" and "time" into a single one.
