generate.design.pl: Plot Sampling Survey Design Specification
In dill/wisp: Wildlife Simulation Package (wisp)

Description Usage Arguments Details Value See Also Examples

Generates a plot sampling survey design, using the parameters in a ‘pars.design.pl’ object.

1	generate.design.pl(pars.design.pl, seed = NULL)

`pars.design.pl`	A plot sampling design parameter object returned by the function `setpars.design.pl`
`seed`	the number passed to set.seed() to initialise random number generator

Whereas ‘setpars.design.pl’ sets up the rules that are used to generate a covered region for a plot sampling survey, this function introduces randomness and generates an actual covered region. The function setpars.design.pl must have been run before ‘generate.design.pl’ is run.

generate.design.pl returns an object of class 'design.pl´ which has the following elements:

setpars.design.pl

pl.reg <- generate.region(x.length = 100, y.width = 50)
pl.dens <- generate.density(pl.reg)
pl.poppars<-setpars.population(density.pop=pl.dens, number.groups = 100, size.method = "poisson",
                               size.min = 1, size.max = 5, size.mean = 1, exposure.method = "beta",
                               exposure.min = 2, exposure.max = 10, exposure.mean = 6, exposure.shape = 1)
pl.pop <- generate.population(pl.poppars, seed=456)
pl.despars<-setpars.design.pl(pl.reg, n.interval.x = 10, n.interval.y = 20,
                              method = "random", area.covered = 0.2)
pl.des <- generate.design.pl(pl.despars, seed=789)
summary(pl.des)
