simpleCJS {actel}R Documentation

Analytical CJS model

Description

Computes an analytical CJS model for a presence/absence matrix.

Usage

simpleCJS(input, estimate = NULL, fixed.efficiency = NULL, silent = TRUE)

Arguments

input

A presence/absence matrix.

estimate

An estimate of the last array's efficiency, between 0 and 1.

fixed.efficiency

A vector of fixed efficiency estimates [0, 1]. length(fixed.efficiency) must match ncol(input).

silent

Logical: Should messages be printed? This argument is mainly intended for function calls running within actel's analyses.

Value

A list containing:

Examples

# prepare a dummy presence/absence matrix
x <- matrix(c(TRUE, TRUE, TRUE, TRUE, FALSE, TRUE, TRUE, TRUE, FALSE), ncol = 3)
colnames(x) <- c("Release", "Array1", "Array2")

# run CJS
simpleCJS(x)
