     sunspot.year

_F_o_r_m_a_t:

     The univariate time series 'sunspot.year' contains 289

_N_o_t_e:

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