_D_e_s_c_r_i_p_t_i_o_n:

     Converts objects from other hierarchical clustering functions to
     class `"hclust"'.

_U_s_a_g_e:

     as.hclust(x, ...)
     as.hclust.twins(x, ...)

_A_r_g_u_m_e_n_t_s:

       x: Hierarchical clustering object

     ...: further arguments passed to or from other methods.

_D_e_t_a_i_l_s:

     Currently there is only support for converting objects of class
     `"twins"' as produced by the functions `diana' and `agnes' from
     the package `cluster'.

_V_a_l_u_e:

     An object of class `"hclust"'.

_S_e_e _A_l_s_o:

     `hclust', `diana', `agnes'

_E_x_a_m_p_l_e_s:

     x <- matrix(rnorm(30), ncol=3)
     hc <- hclust(dist(x), method="complete")

     library(cluster)
     ag <- agnes(x, method="complete")

     x11()
     par(mfrow=c(1,2))
     plot(hc)
     mtext("hclust", side=1)
     plot(as.hclust(ag))
