- type
character string. Compartmental type of the epidemic, i.e. one of "SIR",
"SI", "SIS" or "SIRS".
- size
integer. Size of the epidemic, i.e. the number of initially susceptible
individuals, which became infected during the course of the epidemic.
- initiallyInfected
factor (with the same levels as the id
column in the "epidata"
object). Set of initially infected individuals.
- neverInfected
factor (with the same levels as the id
column in the "epidata"
object). Set of never infected individuals, i.e. individuals, which were
neither initially infected nor infected during the course of the epidemic.
- coordinates
numeric matrix of individual coordinates with as many rows as there are
individuals and one column for each spatial dimension. The row names of
the matrix are the id
s of the individuals.
- byID
data frame with time points of infection and optionally removal and
re-susceptibility (depending on the type
of the epidemic) ordered
by id
. If an event was not observed, the corresponding
entry is missing.
- counters
data frame containing all events (S, I and R) ordered by time. The columns
are time
, type
(of event), corresponding id
and the
three counters nSusceptible
, nInfectious
and nRemoved
.
The first row additionally shows the counters at the beginning of the
epidemic, where the type
and id
column contain missing values.
