Calculate reproduction number for a multigroup model with a given state of vaccination and immunity

Usage

vaxrepnum(meaninf, popsize, trmat, initR, initV, vaxeff)

meaninf: mean infectious period with same time units as trmat
popsize: the population size of each group
trmat: matrix of group-to-group (column-to-row) transmission rates
initR: initial number of each group already infected and immune
initV: initial number of each group vaccinated
vaxeff: effectiveness (0 to 1) of vaccine in producing immunity to infection
