## Further Information

- For this app, the underlying function running the simulation is called `simulate_idpatterns.R`. You can call this function directly, without going through the shiny app. Check the help file for the function for more information.
- If you call the function directly, you need to process the results returned from this function and produce useful output (such as a plot) yourself.
- You could also modify this R function for your own purposes, though that requires experience writing R code. To find out how to do that, type `?DSAIDE` at the R console.
- For some papers discussing ID patterns and seasonality, see e.g. (Dowell 2001, Altizer et al. (2006)).
