I am sorry you are running into an issue. I'd be more than happy to help you resolve it though. Dan is right, if you could post an issue for us and provide some more information (what version of ArcMap are you using?, what version of R do you have?, and what version of the R-ArcGIS bridge are you using?) we can get to work at checking on what is going on.
Sorry again about the problem, hope to hear from you soon.
