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.
