Hello all, I am currently trying to create my first package in mathematica 8.0. I tried the reference package from http://reference.wolfram.com/mathematica/tutorial/SettingUpMathematicaPackages.html, which worked without a problem. In my own package, I would like to use the package combinatorica for the numbers of vertices of a graph V[G], since I would like to create multiple arrays with V[G] entries. So I tried the following: ---------------------------- BeginPackage["karl`"] Needs["Combinatorica`"] Begin["`Private`"] karl[G_]:=Array[numberone, V[G]]; Array[numbertwo, V[G]]; End[ ] ---------------------------- Which gave me the following message: Array::ilsmn: "Single or list of non-negative machine-sized integers expected at position 2 of Array[numbertwo,V[G]]. " EndPackage[ ] I then tried karl[G_Graph] to see if that fixed it, but the same error occurs. Can someone see my error or suggest a fix? Thank you :-) Many greetings, Karl Schulz
