[R] Question on creating Date variable

[Christofer Bogaso]

Hello all,

Let say I have following (numeric) vector:

 > x
  [1] 11.00 11.25 11.35 12.01 11.14 13.00 13.25 13.35 14.01 13.14 14.50 
14.75 14.85 15.51 14.64

Now, I want to create a 'Date' variable (i.e. I should be able to do all 
calculations pertaining to date/time and also time-series plotting etc.) 
like

2012-12-31 11:00:00 AM, 2012-12-31 11:25:00 AM, 2012-12-31 11:35:00 AM, 
2012-12-31 12:01:00 PM, . . . .


Is it possible to achieve that?

Thanks and regards,
