#' Make state transitions using Rcpp.
#'
#' Take in the matrix of the states of synthetic population (created by \code{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.
#'
#' @param origin A number which represents the column index \code{s.matrix} you want to do the transition from
#' @param new.states A numeric vector or a number which represents the column index \code{s.matrix} you want
#' as the destination(s) for the transition
#' @param params A numeric vector of similar length to \code{new.states} which serves as the transition rate(s)
#' @param s.matrix A state matrix created from \code{syn_pop} function
#' @return A transition matrix of the same dimension as \code{s.matrix}. -1 indicates that the individual has left
#' the corresponding state. +1 indicates that the individual has become the corresponding state.
#' @examples

#' stRCPP(1,2,.1,pop)
