stRCPP: Make state transitions using Rcpp.

In ibmcraftr: Toolkits to Develop Individual-Based Models in Infectious Disease

Description

Take in the matrix of the states of synthetic population (created by syn_pop function) and calculate the transitions from one state to other state(s) using the transition probabilities [not rate(s)]. The major difference from the R alone version was that instead of having the transition rate(s), transition probabilities are used. These probabilities will thus be calculated with another function.

Usage

stRCPP(origin, new.states, params, s.matrix)

Arguments

origin	A number which represents the column index s.matrix you want to do the transition from
new.states	A numeric vector or a number which represents the column index s.matrix you want as the destination(s) for the transition
params	A numeric vector of similar length to new.states which serves as the transition rate(s)
s.matrix	A state matrix created from syn_pop function

Value

A transition matrix of the same dimension as s.matrix. -1 indicates that the individual has left the corresponding state. +1 indicates that the individual has become the corresponding state.

Examples

pop <- syn_pop(c(19,1,0,0))
stRCPP(1,2,.1,pop)
