simulated_epidemics {epiphy} | R Documentation |
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. |
