Instead of repeating yourself, please do some research. There is a Posting Guide mentioned at the bottom of this message. One of the things it mentions is making a reproducible example. (You might find [1] helpful in that regard.) Another thing it mentions is posting in plain text, which does not get mangled in transit. Another useful but of advice is to cc the package maintainer in case they are not monitoring R-help (see ?maintainer).

Keep in mind that there are over 6000 contributed packages out there, so making it easy for someone familiar with R but not familiar with your special package is an important strategy in getting help. In addition, if this turns out to be a bug that the maintainer needs to fix then they will need a reproducible example in order to do that.
