In epiphy: Analysis of Plant Disease Epidemics

Examples of simulated epidemic data.

Description

Epidemics were generated using the stochastic simulator from Xu and Madden (2004). The data consist of the numbers of diseased plants per sampling unit (out of a total of n = 100 plants in each sampling unit). N = 144 sampling units, and different values for the parameters pattern and mu were used for the simulations.

Usage

simulated_epidemics

Format

A data frame with 864 rows and 6 variables:

[, 1]	pattern	Either clumped (i.e. aggregated), random or regular.
[, 2]	mu	Median spore dispersal parameter.
[, 3:4]	x,y	Grid spatial coordinates.
[, 5]	i	Number of diseased plants (from 0 to 100).
[, 6]	n	Sampling unit size. Here, n = 100 plants per sampling unit.
