_D_e_s_c_r_i_p_t_i_o_n:

     For a given GO category or KEGG pathway, all probes in the
     supplied data are mapped to the pathway and a heatmap is produced.

_U_s_a_g_e:

     GO2heatmap(x, eset, data, ...)
     KEGG2heatmap(x, eset, data, ...)

_A_r_g_u_m_e_n_t_s:

       x: The name of the category or pathway. 

    eset: An 'exprSet' providing the data. 

    data: The name of the chip.

     ...: Additional parameters to pass to 'heatmap'. 

_D_e_t_a_i_l_s:

     For the given pathway or GO category all matching probes are
     determined, these are used to subset the data and 'heatmap' is
     invoked on that set of data. Extra parameters can be passed
     through to 'heatmap' using the '...' parameter. The 'annotation'
     slot of the 'eset' argument is used to determine the appropriate
     annotation data to use.

_V_a_l_u_e:

     The value returned by 'heatmap' is passed back to the user.

_A_u_t_h_o_r(_s):

     R. Gentleman

_S_e_e _A_l_s_o:

     'heatmap'

_E_x_a_m_p_l_e_s:

      if( require("hgu95av2") ) {
       data(sample.ExpressionSet)
       KEGG2heatmap("04810", sample.ExpressionSet, "hgu95av2")
      }
