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...
Ask plot not to produce an axis, then construct the labels yourself and
add them. The axis.POSIXct() function will be helpful in this.

Hi, I'd suggest you use dotchart() instead of plot(). I believe this
is what you expected:
dotchart(value, time)

Thanks a lot
