_D_e_s_c_r_i_p_t_i_o_n:

     These generic functions access the expression and error
     measurements of assay data stored in an object derived from the
     'eSet-class'.

_U_s_a_g_e:

     exprs(object)
     exprs(object) <- value
     se.exprs(object)
     se.exprs(object) <- value

_A_r_g_u_m_e_n_t_s:

  object: Object derived from class 'eSet'.

   value: Matrix with rows representing features and columns samples.

_V_a_l_u_e:

     'exprs' returns a (usually large!) matrix of expression values;
     'se.exprs' returns the corresponding matrix of standard errors,
     when available.

_A_u_t_h_o_r(_s):

     Biocore

_S_e_e _A_l_s_o:
