clone: Replicate Rows

Description

Clone rows of a 2-D object a constant or random number of times

Usage

## S3 method for class 'default':
clone(object, type, ...)
  ## S3 method for class 'popn':
clone(object, type, ...)

Arguments

object

any object

type

character 'constant', 'poisson' or 'nbinom'

...

other arguments for distribution function

Value

Object of same class as object but with varying number of rows. For clone.popn an attribute `freq' is set, a vector of length equal to the original number of rows giving the number of repeats (including zeros). If popn is a multi-session population the returned value will be a multi-session population of the same length.

Details

The ...argument specifies the number of times each row should be repeated. For random distributions (Poisson or negative binomial) ...provides the required parameter values: lambda for Poisson, size, prob or size, mu for negative binomial. One application is to derive a population of cues from a popn object, where each animal in the original popn generates a number of cues from the same point.

Examples

Run this code

## population of animals at 1 / hectare generates random
## Poisson number of cues, lambda = 5
mics4 <- make.grid( nx = 2, ny = 2, spacing = 44, detector = "signal")
pop <- sim.popn (D = 1, core = mics4, buffer = 300, nsession = 66)
pop <- clone (pop, "poisson", 5)
attr(pop[[1]],"freq")
