as.epidata: Discrete Time level information of an Epidemic
In EpiILM: Spatial and Network Based Individual Level Models for Epidemics

Description Usage Arguments Value See Also Examples

This function allows the user to generate objects of class "epidata". The output of this function provides information required to be used in the other functions in the package.

1	as.epidata (type, n, x = NULL, y = NULL, inftime, infperiod = NULL, contact = NULL)

`type`	Type of compartment framework, with the choice of "SI" for Susceptible-Infectious diseases and "SIR" for Susceptible-Infectious-Removed.
`n`	Population size
`x`	X coordinates of individuals.
`y`	Y coordinates of individuals.
`inftime`	Times at which individuals are infected to initialize epidemic simulation.
`infperiod`	Length of infectious period for each individual.
`contact`	A contact network matrix or an array of contact network matrices.

An object of class epidata is returned containing the following:

type: Type of compartment framework, with the choice of "SI" for Susceptible-Infectious diseases and "SIR" for Susceptible-Infectious-Removed.
XYcoordinates: The XY-coordinates of individuals if distance-based ILM is used, otherwise is NULL.
contact: Contact network matrix if network-based ILM is used, otherwise is NULL.
inftime: The infection times of individuals.
remtime: The removal times of individuals when type = “SIR”.

epidata, plot.epidata.

# generate 100 X-Y coordinates for a distance-based ILM

x <- runif(100, 0, 10)

y <- runif(100, 0, 10)

# suppose we know the infection times for a spatial SI model based on above X-Y coordinates

inftime  <- rpois(100, 8) 

# Now we can convert above information to an epidata object with

out <- as.epidata(type = "SI", n = 100, x = x, y = y, inftime = inftime )
