init.dcm {EpiModel}

R Documentation

Initial Conditions for Deterministic Compartmental Models

Description

Sets the initial conditions for deterministic compartmental models simulated with dcm.

Usage

init.dcm(s.num, i.num, r.num, s.num.g2, i.num.g2, r.num.g2, ...)

Arguments

`s.num`	Number of initial susceptible persons. For two-group models, this is the number of initial group 1 susceptible persons.
`i.num`	Number of initial infected persons. For two-group models, this is the number of initial group 1 infected persons.
`r.num`	Number of initial recovered persons. For two-group models, this is the number of initial group 1 recovered persons. This parameter is only used for the `SIR` model type.
`s.num.g2`	Number of initial susceptible persons in group 2. This parameter is only used for two-group models.
`i.num.g2`	Number of initial infected persons in group 2. This parameter is only used for two-group models.
`r.num.g2`	Number of initial recovered persons in group 2. This parameter is only used for two-group `SIR` models.
`...`	Additional initial conditions passed to model.

Details

The initial conditions for a model solved with dcm should be input into the init.dcm function. This function handles initial conditions for both base model types and original models. For an overview of initial conditions for base DCM class models, consult the Basic DCMs tutorial.

Original models may use the parameter names listed as arguments here, a new set of names, or a combination of both. With new models, initial conditions must be input in the same order that the solved derivatives from the model are output. More details on this requirement are outlined in the Solving New DCMs tutorial.
