`x` |
A matrix, usually including one or more |

Function `marginals()`

takes a matrix and returns a list holding
the marginal totals and the coordinates of blank squares.

Function `dof()`

takes a board and returns the number of degrees
of freedom present.

Function `.Cargs()`

takes a matrix and coerces it to a list
suitable for calling the `C++`

routines; it is not really
intended for the end-user. This function uses formal S4 methods to
coerce a matrix to an object of class `board`

(checking for
non-integer entries, etc), as do the functions documented in
`allboards.Rd`

.
