sim2sidetf: Simulate data from camera trap SCR study with partial...

Description Usage Arguments Value Author(s)

View source: R/sim2sidetf.R

Description

See the sim2side help file for a description of the capture process. The camera failure process operates like this: cameras fail with probabilty failprob and remain disabled for faildur occasions. If failtype=1, traps at single sites fail together (bear attack?) and if failtype=2, they fail independently. This function was written to investigate the importance of using the 2D trap operation file.

sim2sidetf(N = 120, lam01 = 0.1, lam02 = 0.2, sigma = 0.5,
  K = 10, X = X, buff = 3, failprob = 0.05, faildur = 2,
  failtype = 2, obstype = "bernoulli")

Arguments

N

a vector indicating the number of individuals to simulate

lam01

the single side detection function hazard rate

lam02

the double side detection function hazard rate

sigma

the spatial scale parameter

K

the number of capture occasions

X

the K x 3 matrix of trap locations and number of cameras at each trap. columns are X, Y, #cams

buff

the distance to buffer the trapping array in the X and Y dimensions to produce the state space

failprob

the probability a camera or set of cameras at a site will fail on each occasion

faildur

the number of occasions a camera remains inoperable

failtype

1 if cameras at a site fail together and 2 if they fail independently

obstype

observation type, either "bernoulli" or "poisson"

Value

a list containing the both, left, and right data sets, the both plus left only and both plus right only data sets (stored in y.obs), the activity centers, the trap object, and several other data objects and summaries.
