cross | R Documentation |

This operation is useful in recursively generating all the possible path histories of a sequential design.

cross(A, v)

`A` |
An arbitrary matrix |

`v` |
An arbitrary vector |

For each component of v, the matrix A is duplicated with an extra right column equal to v[i]. This is added to the current output until the components of v are exhausted.

A matrix with dim(A)[2]+1 columns and dim(A)[1]*length(v) rows.
