as.record: Transform observed data to ascertainment records

Description

Transform observed data to ascertainment records.

Usage

as.record(x)

Arguments

x

the matrix of the observed capture histories

Value

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	[1,]	0

Examples

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