Time series analysis with external events in R

[mmz]

I have a time series of daily website visitors and several different marketing events (some continuous for several days). I would like to determine what impact did those marketing events have on website visitors dynamics. What approach would you suggest in terms of analysis ? I'm working with R.

Thanks in advance

I would suggest interupted time series (ideally with a control although that is hard to do in practice). Hays et el did a nice sage monograph on this - you might want to look that up.

Thank you! I thought similar.
