_D_e_s_c_r_i_p_t_i_o_n:

     Given a two-sample test statistic and an exprSet this function
     plots regions of the genome that are either highly expressed (in
     red) or have low expression (blue) differentially in the two
     groups.

_U_s_a_g_e:

     amplicon.plot(ESET, FUN, genome)

_A_r_g_u_m_e_n_t_s:

    ESET: an object of class 'exprSet'

     FUN: A two sample test function suitable for 'esApply'. 

  genome: A character string of the base name for the annotation. 

_D_e_t_a_i_l_s:

     In some genetic studies we are interested in finding regions of
     the genome where there are a set of highly expressed genes in some
     subgroup of the population. This set of highly (or lowly)
     expressed genes is often of great interest. For example in breast
     cancer the HER-2 gene is on an amplicon. In some patients
     approximately 5 genes located near HER-2 are all amplified.

     These plot should help in the search for such regions.

_V_a_l_u_e:

     No value is returned. This function is executed purely for side
     effect.
