Re: [R] Agent-based social simulation and R
Hi Tom, you may have a look at the CRAN package simecol, that has some examples how to implement different types of dynamic models in R (differential equations, grid models, individual based models). Individual-based models (IBMs) are a model family used in ecology, which are in its essence almost the same as ABMs in other areas. See http://simecol.r-forge.r-project.org for the package, examples, pdf's, and in particular the useR!2008 slides. Thomas Petzoldt Tom Backer Johnsen wrote: Do anyone know anything about the use of R for agent-based social simulation? It should be possible, and would be convenient for the simple reason that there are several nice packages containing useful stuff for SNA (Social Network Analysis). Information about packages, web sites, experienced persons in the field, etc. would be very welcome.

I wil have to seriously consider that tool. Thanks.

For the time being the prime candidate in the R world seems to be the igraph package, which is oriented towards graph theory and SNA, something that would be convenient (less programming).

I've learned this strategy from Pietro Terna - http://web.econ.unito.it/terna/ Thank you for useful information and suggestions. I will certainly look into what you mention. I am at the moment looking at the igraph package, which seems to have what I need, and includes visualization as well. As for Python, that is nice, but if I can do most of what I want in R, I would prefer that.

I'll have to look trough the code. How far away do the agents see? Anything beyond their immidiate neighbors?

This puts the neighborhood model to the 'hardest' test. Yet the demo code also contains some other possibilities.
