Such issues are probably best for R-devel.

There is nothing to reproduce here, which could well be considered a bug 
in your posting.

It seems likely that your package's documentation has an alias for 
'vowel.test' in a man page marked as \docType{data}, yet 
data('vowel.test') does not work.  That seems like a bug in your package.
Using LazyData makes such things much more consistent.
