[R] How to show complete time values in a plot x axis

[Sébastien Durand]

Dear Yihui,

The resulting plot produced by dotchart is not what I wish for!
I need to produce a time axis that is consequent to the time values.
When dotchart is used, time values are simply considered as labels.
What I wish for is a way to produce a numerical time axis that really 
takes into account the given time values. With plot I have been able to 
do so, the only issue is the labelling.
I wish to represent the complete time on the axis ticks...

Cheers
