Generates all points on a (p,n) simplex lattice (i.e. a p-part composition of n).
Generates all points on a p,n simplex lattice (i.e. a p-part composition of n). Each point is represented as x, a p-dimensional vector of nonnegative integers that sum to n. If argument "fun" is not null, applies a function given by the argument to each point. If simplify is FALSE, returns a list; else returns a vector or an array. "..." are passed unchanged to function given by argument fun, if any.
