Identifies the rows of a matrix that only show one level.

1	identifyMonomorphism(x)

`x`	a matrix consisting of integers between 1 and n.cat, where n.cat is the number of levels the variables in `x` can take. Each row of `x` is assumed to represent one variable. Missing values are allowed.

Numeric vector containing the rows of x showing only one level.
