Preheat oven to 350 F.
In a large mixing bowl, cream together the cream cheese and sugar until light and fluffy.
Beat in the sweet potato and eggs. Stir in the biscuit mix, cinnamon, nutmeg, and cranberries until just blended.
Turn into a 9x5x3" loaf pan coated with nonstick cooking spray. Bake for 45 minutes to 1 hour, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 15 minutes, and serve.
