Takes a character string representation of a factorial effect in PG(n-1,2)
, and returns a binary vector of length n. This can be used in defining a spread or a star. The spread/star should be formatted as a 3-dimensional array with spread[i,j,k]
/star[i,j,k]
indicating whether or not the i
th basic factor is present in the j
th effect of the k
th flat of spread
/star
. See Spencer et al. (2019) for details.
A binary vector of length n.
