Sorry, I meant, of course:
# sets vaccination to 0 (not rate nu !!!)
eventfun <- function(t, Omega, parameters) {
with(as.list(c(Omega,parameters)),{
return(list(c(S, E, I, D, V=0))
})
}
# or alternatively:
eventfun <- function(t, Omega, parameters) {
return(list(c((Omega[1:4], V=0)))
}
i.e. the states (e.g. V) not the derivatives (dV)
