## Plotting a count process

 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 ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Forgetting about the dates now, this would do it. x = floor(pmax(rnorm(30,5,2),1)) xcum = cumsum(x) plot(xcum,1:30) Dieter ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
