Hi there,

Some others have had similar error issues with lazy-load database. Have you
tried restarting R? That's what the users recommend in this thread:
http://r.789695.n4.nabble.com/weird-error-with-a-lazyload-RData-file-in-a-package-td4662836.html
.

I don't have the same issue with the release, nor, developer versions.

Best,


 - Joseph Paulson
