hello everybody,
i want to plot a count process in the following way, but i don't know
how i can do that. i have data for example x<(0,2,6,2,8,4,.....) and
dates y which is a vector of weekly dates for example
(01/01/06, 08/01/06, 15/01/06, 22/01/06, ....), now i want to plot the
y's an the horizontal axis. On each date the count process jumps upwards
1 unit, so the vertical axis is 0, 1, 2, 3, ......
the distance between the dates is shown in vector x, so for example the
distance between 08/01/06 and 15/01/06 should be 2. maybe i can use some
times series functions for doing this?
i would be very thankful for any advice.
best regards
Andreas

If I understand you correctly, this means plotting equidistant point against
the cumulative sum. Forgetting about the dates now, this would do it.
x = floor(pmax(rnorm(30,5,2),1))
xcum = cumsum(x)
plot(xcum,1:30)

Thank you for your advice, but this is not the exaxt thing i'm looking for
http://robotics.caltech.edu/~zoran/Research/poisson/img1.pngthis 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.

Now my problem is solved, i thinked a while about it and rearanged my
plot in the following way for everybody how is interested
x<0:3
y<c(0,5,8,3)
dates<c("","01.01.05","08.01.05","15.01.05")
plot(x,cumsum(y),type="p",axes=FALSE,xlab="Date",ylab="Failure
Number",pch=20)
axis(side = 1,0:3 ,labels = dates)
axis(side = 2)
box()
i<seq(along=x)
segments(x[i],cumsum(y)[i],x[i+1],cumsum(y)[i])
segments(x[length(x)],cumsum(y)[length(y)],x[length(x)]+1,cumsum(y)[length(y)])
