_D_e_s_c_r_i_p_t_i_o_n:

     These generic functions access feature data (experiment specific
     information about features) and feature meta-data (e.g.,
     descriptions of feature covariates).

_U_s_a_g_e:

     featureData(object)
     featureData(object) <- value
     fData(object)
     fData(object) <- value
     fvarLabels(object)
     fvarLabels(object) <- value
     fvarMetadata(object)
     fvarMetadata(object) <- value

_A_r_g_u_m_e_n_t_s:

  object: Object, possibly derived from 'eSet-class' or
          'AnnotatedDataFrame-class'.

   value: Value to be assigned to corresponding object.

_V_a_l_u_e:

     'featureData' returns an object containing information on both
     variable values and variable meta-data.  'fvarLabels' returns a
     character vector of measured variable names. 'fData' returns a
     data frame with features as rows, variables as columns.
     'fvarMetadata' returns a data frame with variable names as rows,
     description tags (e.g., unit of measurement) as columns.

_A_u_t_h_o_r(_s):

     Biocore

_S_e_e _A_l_s_o:

     'eSet', 'ExpressionSet'
