Creates needed constructs from the release-recapture history.
process.ch(ch, freq = NULL, all = FALSE)number of capture occasions
absolute value of frequency for each ch
vector of occasion numbers for first 1
vector of occasion numbers for last 1
vector of indicators of a loss on capture if set to 1
capture history matrix
1's from first (1) to last (1) and 0's elsewhere; only if all==TRUE
1's from occasion after first (1) to nocc(last occasion); only if all==TRUE
1's from occasion after last (1) to nocc; only if all==TRUE
1's from last (1) to nocc; only if all==TRUE
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.
Optional vector of frequencies for ch; if missing assumed to be a; if <0 indicates a loss on capture
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.
