as.record: Transform observed data to ascertainment records

In CARE1: Statistical package for population size estimation in capture-recapture models.

Description

Transform observed data to ascertainment records.

Usage

as.record(x)

Arguments

x	the matrix of the observed capture histories

Details

x has one row per unit captured in the experiment. Each row is an observed capture history. It must contain only zeros and ones; the number one indicates a capture. In this case, the number of columns in the table represents the number of capture occasions in the experiment (noted t). Here is a fictive example of a data set of this type for t=3:

[1,]	0	1	0
[2,]	1	0	1
[3,]	0	1	0
[4,]	0	1	1
[5,]	1	0	1
[6,]	1	0	1
[7,]	0	0	1
[8,]	0	1	0
[9,]	0	1	0
[10,]	1	1	0

Value

the vector of capture histories or ascertainment records.

Examples

x=matrix(sample(0:1,300,TRUE),ncol=3)
as.record(x)
