Marginals of a board

Various utilities to calculate the marginal totals of a board.

Keywords: array

Usage

marginals(x)
dof(x)
is.board(x)
as.board(x)
.Cargs(x)

Arguments

x: A matrix, usually including one or more NA entries, coerced to integer (a board); see details section

Details

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.
