u0_SEIR | R Documentation |
Example data to initialize a population of 1600 nodes and
demonstrate the SEIR
model.
u0_SEIR()
A data.frame
with the number of individuals in the
‘S’, ‘E’, ‘I’ and ‘R’ compartments in
1600 nodes. Note that the ‘E’, ‘I’ and ‘R’
compartments are zero.
A data.frame
## Create an 'SEIR' model with 1600 nodes and initialize it to ## run over 4*365 days and record data at weekly time-points. ## Add ten infected individuals to the first node. u0 <- u0_SEIR() u0$I[1] <- 10 tspan <- seq(from = 1, to = 4*365, by = 7) model <- SEIR(u0 = u0, tspan = tspan, events = events_SEIR(), beta = 0.16, epsilon = 0.25, gamma = 0.01) ## Run the model to generate a single stochastic trajectory. result <- run(model) plot(result) ## Summarize trajectory summary(result)
