Hi, I would like to know how you are calming down the R check. I've an issue
with the `head` method. I'm incorporating a head for data base, but nothing
that I add in the function file seems to be able to silence the R check. Below
is what I have:
checking S3 generic/method consistency ... NOTE
Found the following apparent S3 methods exported but not registered:
head.SQLiteConnection
So register it as an S3 method in your NAMESPACE file.
