Your post is unlikely to solicit a helpful response. As you do not adhere to the posting guide, it is quite impossible for us to figure out from your description what is going wrong. Please provide a self-contained example that reproduces the problem (i.e., code with simulated or actual data that we can copy paste to the R-prompt). Moreover, chances are that when you try to reproduce the error with simulated code, you will figure out what your mistake is.
