\begin{Note}\relax
Prior to \R{} 2.0.0 \code{sunspot.year} and \code{\LinkA{sunspot.year}{sunspot.year}}
were copied to the user's workspace (or elsewhere) by
\code{data(sunspot)}. However, as package \pkg{lattice} has a dataset
\code{sunspot} which can be retrieved by the same command, that usage
has been removed.
