unmarkedFrameOccuFP {unmarked}

Organize data for the single season occupancy models fit by occuFP

Description

Organizes detection, non-detection data along with the covariates. This S4 class is required by the data argument of occu and occuRN

Usage

unmarkedFrameOccuFP(y, siteCovs=NULL, obsCovs=NULL, type, mapInfo)

Arguments

y

An RxJ matrix of the detection, non-detection data, where R is the number of sites, J is the maximum number of sampling periods per site.

siteCovs

A data.frame of covariates that vary at the site level. This should have M rows and one column per covariate

obsCovs

Either a named list of data.frames of covariates that vary within sites, or a data.frame with RxJ rows in site-major order.

type

A vector with 3 values designating the number of occassions where data is of type 1, type 2, and type 3 - see occuFP for more details about data types.

mapInfo

Currently ignored

Details

unmarkedFrameOccuFP is the S4 class that holds data to be passed to the occu and occuRN model-fitting function.

Value

an object of class unmarkedFrameOccuFP

o = 10
o1 = 5
y = matrix(0,n,o)
p = .7
r = .5
fp = 0.05

y[1:(n*.5),1:(o-o1)] <- rbinom((o-o1)*n*.5,1,r)
y[(n*.5+1):n,(o-o1+1):o] <- rbinom((n*o1*.5),1,fp)
type <- c((o-o1),o1,0)  ### vector with the number of each data type
site <- c(rep(1,n*.5*.8),rep(0,n*.5*.2),rep(1,n*.5*.2),rep(0,n*.8*.5))

site <- data.frame(habitat = site)
occ <- list(METH = occ)
