Sorry, but I haven't yet. The truth as (as @jcblum mentioned) is that our time is quite limited and the more you can do to ease our ability to debug these problems, the better. The ideal is that you can give us a bit of standalone R code that we can copy + paste into our own RStudio sessions, and that bit of code will be sufficient to reproduce the issue.
If the code example absolutely needs to depend on external data, you can consider uploading the data somewhere publicly accessible (e.g. GitHub), and then the code provided could use download.file() to retrieve it.
