generate.design.cr: Survey design of mark-recapture method

In dill/wisp: Wildlife Simulation Package (wisp)

Description

Generates a mark-recapture survey design.

Usage

        generate.design.cr(reg, n.occ = 2, effort = rep(1, n.occ))

Arguments

reg	object of class 'region´.
n.occ	number of survey (capture) occasions.
effort	vector specifying level of effort used on each survey occasion.

Details

The function generates a mark-recapture method design object specifying the number of capture occasions and effort levels used on each occasion. The effect of the effort levels in terms of catchability is determined by the capture function, which is specified using ‘setpars.survey.cr’. Conceptually, the function ‘generate.design.cr’ involves only the aspects of the mark-recapture survey that are directly under the control of those doing the survey. The function setpars.survey.cr sets the parameters of the parts of the survey that involve some randomness.

Value

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

region	object of class 'region´
number.occasions	number of survey occasions
effort	vector specifying level of effort used on each survey occasion
parents	Details of WiSP objects passed to function
created	Creation date and time

Examples

cr.reg<- generate.region(x.length = 50, y.width = 80)
cr.des<- generate.design.cr(cr.reg, n.occ = 4, effort = c(5,4,3,2))
summary(cr.des)
