[R] Plotting a count process

[voodooochild@gmx.de]

Thank you for your advice, but this is not the exaxt thing i'm looking for
http://robotics.caltech.edu/~zoran/Research/poisson/img1.png
this picture gives an example what i want to get. instead of t0, t1, 
t2,.... i want to draw my dates.
In my description i forgot the the horizontal line, which indicates the 
time between two dates each, sorry for that.

regards
andreas
