R CMD check returns NOTE about package data set as global variable

I'm developing a package that comes with a data set called RutgersMapB36. One of the package's functions requires this data frame. A toy example is:

test<-function() {
   data(RutgersMapB36)
   return(RutgersMapB36[,1])
}


R CMD check returns a NOTE:

test: no visible binding for global variable 'RutgersMapB36'

Is there any way to avoid this NOTE?

Thanks,

Brad
