Is f1 nested within f2?

Does every level of f1 occur in conjunction with exactly one level of f2? The function is based on converting a triplet sparse matrix to a compressed column-oriented form in which the nesting can be quickly evaluated.

Usage
isNested(f1, f2)
Arguments
f1

factor 1

f2

factor 2

Value

TRUE if factor 1 is nested within factor 2
