Return the rate of reproduction (amount per unit time)
reproFuncDefault(x, time, species, strain)Vector of state variables within the DDE solver. To access a variable use: x$speciesName['stageName',strainNumber] e.g. for species 'Bacteria', stage 'reproductive', strain 2 use x$Bacteria['reproductive',2] If there is only one stage and strain in species 'Food', for example, use x$Food[1,1]
(scalar). The current time point in the DDE solver.
(integer). The numbered species for which to return a reproductive rate.
(integer). The numbered strain for which to return a rate.
Reproduction rate (amount per unit time) for the strain, species and time specified.
Unlike the other RateFunctions this rate function has
no stage argument as by definition it only pertains to the first
stage of life
