I have a DateTime vector within a data.frame where the data frame is made up of 8760 observations representing hourly intervals throughout the year e.g.

2010-01-01 00:00
2010-01-01 01:00
2010-01-01 02:00
2010-01-01 03:00

and so on.

I would like to create a data.frame which has the original DateTime vector as the first column and then the hourly values in the second column e.g.

2010-01-01 00:00          00:00
2010-01-01 01:00          01:00

How can this be achieved?
