_D_e_s_c_r_i_p_t_i_o_n:

     This dataset gives the number of hurricanes per year (from 1925 to
     1995) as well as the ENSO state and total monetary damage.

_U_s_a_g_e:

     data(Rsum)

_F_o_r_m_a_t:

     A data frame with 71 observations on the following 4 variables.

     _Y_e_a_r a numeric vector giving the year.

     _E_N a numeric vector giving the ENSO state (-1 for La Ni\~{n}a, 1
          for El Ni\~{n}o and 0 otherwise).

     _C_t a numeric vector giving the number of hurricanes for the
          corresponding year.

     _T_D_a_m a numeric vector giving the total monetary damage (millions
          of U.S. dollars).

_D_e_t_a_i_l_s:

     More information on these data can be found in Pielke and Landsea
     (1998) or Katz (2002).
