_D_e_s_c_r_i_p_t_i_o_n:

     This generic function accesses the 'data.frame' for the
     feature-level data, such as annotation of SNPs or genes.  fData is
     the analog of 'pData' that accesses the 'data.frame' for the
     'phenoData' 'AnnotatedDataFrame-class'.

_U_s_a_g_e:

     fData(object)

_A_r_g_u_m_e_n_t_s:

  object: Object, possibly derived from class 'eSet'

_D_e_t_a_i_l_s:

_V_a_l_u_e:

     'fData' and 'pData' both return data.frames.  'fData' will
     generally return a very large data.frame as the number of features
     is often very large.
