freq_data: Convert capture-recapture configurations into frequency data

Description

Given a matrix of observed capture-recapture configurations, convert the data to a matrix of frequencies having the same number of rows and a number of columns equal to the number of possible configurations.

Usage

freq_data(R,count=rep(1,nrow(R)))

Value

Y

Matrix of frequency of each capture configuration of size n x (2^J)

Arguments

R

Matrix of size n (sample size) x J (number of capture occastions) of observed capture-recapture configurations

count

Vector of counts for each configuration
