sq: Build matrix of binary vectors of a fixed lenght
In LCCR: Latent Class Capture-Recapture Models

Description Usage Arguments Value Author(s) Examples

It creates all possible binary (with elements equal to 0 or 1) vectors of a specified length; these vectors are casted in a matrix having a number of columns equal to the vector length. If required, the binary vectors are constrained to have the same total (sum of their elements).

1	sq(J, t = NULL)

`J`	legnth of binary vectors
`t`	possible fixed total

`M`	matrix containing all binary vectors

Francesco Bartolucci, Antonio Forcina

# build matrix of all possible binary vectors of legnth 5
  M = sq(5)
  
# build matrix of all possible binary vectors of legnth 5 with total equal 2
  M = sq(5,2)
