create_pollen_sources: Pollen sources emission simulation

In briskaR: Biological Risk Assessment

Description

Simulate pollen sources emission for maize crop. The proportion of plants emitting pollen per day (during 12 days) was observed by Frédérique Angevin (Angevin et al. 2008).

Usage

create_pollen_sources(
  sf,
  timeline = 1:61,
  density = runif(1, 7, 11),
  pollen = rgamma(1, shape = 1.6, scale = 1/(2 * 10^-7))
)

create.pollen.sources()

Arguments

sf	A sf object defining sources fields
timeline	Vector of interger. Time units (e.g. days) including the pollen emission (for simulation, default is time.max). Minimal value is a vector of 12 days.
density	Plant density (number of plant by squared meter)
pollen	Pollen production (number of grains by plant)

Value

A matrix indexed by sources ID (in rows) and by time ( in columns) whose rows give the values of pollen emission (number of grains) for every source.
