process.ch {marked}

Process release-recapture history data

Description

Creates needed constructs from the release-recapture history.

Usage

process.ch(ch, freq = NULL, all = FALSE)

Arguments

ch

Vector of character strings; each character string is composed of either a constant length sequence of single characters (01001) or the character string can be comma separated if more than a single character is used (1S,1W,0,2W). If comma separated, each string must contain a constant number of elements.

freq

Optional vector of frequencies for ch; if missing assumed to be a; if <0 indicates a loss on capture

all

FALSE is okay for cjs unless R code used to compute lnl instead of FORTRAN; must be true for js because it returns additional quantities needed for entry prob.

Value

nocc

number of capture occasions

freq

absolute value of frequency for each ch

first

vector of occasion numbers for first 1

last

vector of occasion numbers for last 1

loc

vector of indicators of a loss on capture if set to 1

chmat

capture history matrix

FtoL

1's from first (1) to last (1) and 0's elsewhere; only if all==TRUE

Fplus

1's from occasion after first (1) to nocc(last occasion); only if all==TRUE

Lplus

1's from occasion after last (1) to nocc; only if all==TRUE

L

1's from last (1) to nocc; only if all==TRUE
