.rosso.formula: Rosso equation.

Description

Rosso equation.

Usage

.rosso.formula(N0, Nmax, mu, lambda, base = exp(1))

Value

a function taking as input x (the time) and outputting the value of the Rosso equation.

Arguments

N0

initial population.

Nmax

final/maximum population.

mu

growth rate.

lambda

latency time.

base

the logarithm base used for plot y-scaling. By default, the natural logarithm is used. Set NULL to not scale.

Details

The output result is by default in the form ln(N_t/N0) (with N_t the population at time t). The base used can be modified by specifying the desired base in the base argument. For example, specifying base=10 corresponds to output in the form log_{10}(N_t/N0). It is possible to specify base = NULL to retrieve the normal N_t output.

Examples

f <- .rosso.formula(0.1, 2, 0.2, 5)
f(4)
## [1] 0
f(20)
## [1] 2.32998
