_D_e_s_c_r_i_p_t_i_o_n:

     These generic functions access the phenotypic data (e.g.,
     covariates) and meta-data (e.g., descriptions of covariates
     associated with an experiment.

     phenoData(object)
     phenoData(object) <- value
     varLabels(object)
     varLabels(object) <- value
     varMetadata(object)
     varMetadata(object) <- value
     pData(object)
     pData(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:

     'phenoData' returns an object containing information on both
     variable values and variable meta-data.  'varLabels' returns a
     character vector of measured variables. 'pData' returns a data
     frame with samples as rows, variables as columns. 'varMetadata'
     returns a data frame with variable names as rows, description tags
     (e.g., unit of measurement) as columns.
