In JUANCCI/Epididact: Temporal progress of plant diseases

Description

Comparison of three epidemics (logisic model) at the same plot. from Madden, 2007: a/(1+((a/y0)-1)*exp(-r*x)),

Usage

plot2logis3M(a_1, a_2, y0_1, y0_2, r_1, r_2, maxt)

Arguments

y0_1	Epidemic 1: initial inoculum
y0_2	Epidemic 2: initial inoculum
r_1	Epidemic 1: rate of progress
r_2	Epidemic 2: rate of progress
maxt	epidemic duration (days)

Value

Two logistic curves

Examples

plot2logis3M(1, 0.7,       # Assintote: Epid 1, Epid 2
             0.001, 0.001, # Initial inoculum: Epid 1, Epid 2
             0.4, 0.4,     # Rate of progress: Epid 1, Epid 2
             50)           # Epidemic duration
