Hi, Fraser, I used R2.10.0 (whose beta version is released today) and KEGGgraph1.1.12, and it works just fine. When I used KEGGgraph_1.1.0 on R-2.9, I got the same error message as you got. Anyhow, it seems your version of KEGGgraph seems old, even for R-2.9. You can first try to update your package on R-2.9. If it still doesn't work, you can try to upgrade R to R-2.10. Hope this helps.
