     This function display the genomic events and tests for the
     differences between groups if they are specified.

     plotSummaryProfile(aCGH.obj,
                        response = as.factor(rep("All", ncol(aCGH.obj))),

_A_r_g_u_m_e_n_t_s:

aCGH.obj: an object of aCGH class.

response: categorical phenotype to compare. defaults to all the samples
          being analyzed together. 

  titles: titles for the groups, defaults to the name of the 'response' 

       X: logical indicating whether X needs to be shown 

       Y: logical indicating whether Y needs to be shown 

maxChrom: this parameter controls how many chromosomes will be plotted,
          from 1 to maxChrom.

chrominfo: a chromosomal information associated with the mapping of the
          data. 

_D_e_t_a_i_l_s:

     This function utilizes output of the 'find.genomic.events' by
     plotting it and testing between groups. The test are performed
     using kruskal-wallis rank test.

_S_e_e _A_l_s_o:

     'aCGH' 'find.genomic.events'

_E_x_a_m_p_l_e_s:

     data(colorectal)

     ## Plotting summary of the sample profiles
