Let A be an expanding n x n integer matrix with \det(A)\ = m. A standa
rd digit set D for A is any complete set of coset representatives for
Z(n)/A(Z(n)). Associated to a given 2) is a set T(A, D), which is the
attractor of an affine iterated function system, satisfying T = U (d i
s an element of D) (T + d) It is known that T(A, D) tiles R-n by some
subset of Z(n). This paper proves that every standard digit set D give
s a set T(A, D) that tiles R-n with a lattice tiling.
