Please re-install the package. All contributed packages using new-style 
classes need to be re-installed because the internal representation of 
such classes and methods has changed, see CHANGES TO S4 METHODS in NEWS. 
Doing:

update.packages(checkBuilt = TRUE)

will check your libraries for packages built under previous releases and 
replace them with ones built for the platform release.
