[R] How to seperate date and time into different columns?

[FMH]

Dear All,

I have a series of data in which the first column consist of a combination of date and time, for instance 17 April 2008 at 4.01pm, such data is recorded as:

4/17/2008 16:01 

I'd like to seperate it into four different columns which consist of Day, Month,Year and Time, respectively.

Could someone please advice me on this mater?

Thank you,
Fir
