matrixToMarray: Transformation of the tt matrix of a relation

Description

The matrix representation of a relation is converted to the array representation or product space representation.

Usage

matrixToMarray(tt, valuenames)

Value

mtt The array (product space) representation of the tt matrix.

Arguments

tt

A (0,1)-matrix or a boolean matrix establishing the relation between two or more variables. The matrix is constructed by placing the variables side by side, as in a truth table representation.

valuenames

A list of the names of the variables with the name of each value of their frame of discernment.

Examples

# Define  wr_tt, a matrix describing the relation between two variables
wr_tt <- matrix(c(1,rep(0,3),rep(c(1,0),3),0,1,1,1,0,0,
1,0,rep(1,5),0,1,1,0,rep(1,5)), ncol=4, byrow = TRUE)
colnames(wr_tt) <- c("Wy Ry", "Wy Rn", "Wn Ry", "Wn Rn")
rownames(wr_tt) <- nameRows(wr_tt)
vars = list( RdWorks = c("Wy", "Wn") , Rain = c("Ry", "Rn"))
print(zmToa <- matrixToMarray(tt = wr_tt, valuenames = vars ) )
