Diffusing across a lattice

Ok, great! That’s made a nice little lattice network. Next we want to -play a diffusion process on this network. To do this, we just -need to run play_diffusion(), and assign the result. Then -we can investigate the resulting object in a few ways. The first way is -simply to print the result by calling the object. The other way is to -unpack the result by calling for its summary.

+play a diffusion process on this network. To do this, we need +to run play_diffusion(). This function plays a simple +contagion process on a network, where any contact with an +infected/adopter node is enough to cause susceptible nodes to +adopt/become infected by the following timepoint. The function returns a +network object that contains information about how the diffusion played +out. Then we can investigate the diffusion process by extracting this +information using as_changelist() and +as_diffusion(). The first simply extracts the list of +adoption/infection events, while the second summarises the diffusion +process by time point.

The secondary report, summary(lat_diff), presents a list -of the events at each time point. In the event variable, the ‘I’ -indicates that these are all infection/adoption events.
