freq_data function

Convert capture-recapture configurations into frequency data

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.

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

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

Returns

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