Computes the sum of absolute differences between two lists using diff_vecs().
diff_lists(l1, l2, name = NULL)A list.
A list.
A string, default to NULL. If not NULL, computes the differences in the l1[[name]] and l2[[name]].
Returns the sum of absolute differences between l1 and l2 if name is NULL, or that between l1[[name]] and l2[[name]] otherwise. If name is not NULL and if name is in exactly one of l1 and l2, returns Inf; if name is in neither, returns NA. Exception: Returns a positive integer if the two elements compared hold NA, NULL or Inf values in different places.
