spn_T_lifecycle_node {MGDrivE2}

Make Transitions (T) For a Node (Mosquitoes only)

Description

This function makes the set of transitions (T) for a SPN. It is used alone if our model is a single-node metapopulation for mosquito dynamics only; otherwise it is used as part of other functions to make SPN models with larger state spaces (metapopulation models, see spn_T_lifecycle_network).

Usage

spn_T_lifecycle_node(spn_P, params, cube)

Arguments

spn_P

set of places produced by spn_P_lifecycle_node

params

a named list of parameters (see details)

cube

an inheritance cube from the MGDrivE package (e.g. cubeMendelian)

Details

This function takes the places produced from spn_P_lifecycle_node and builds all possible transitions between subsets of those places.

The params argument supplies all of the ecological parameters necessary to calculate equilibrium values. This function requires the nE, nL, and nP parameters to be specified. For more details, see equilibrium_lifeycle

While this function produces all structural information related to transitions, hazards are produced by a separate function, spn_hazards.

For examples of using this function, see: vignette("lifecycle-node", package = "MGDrivE2")

Value

a list with two elements: T contains transitions packets as lists, v is the character vector of transitions (T)
