R devel - Apr 2012 - 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

Use data("RutgersMapB36"), which many think is good practice in code.

Is the dataset something that package users will need, or just your
package's functions?
