_D_e_s_c_r_i_p_t_i_o_n:

     This function allow to visualize the histogram of raw p-value
     distribution generated by limma analysis.

_U_s_a_g_e:

     rawpCheck()

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

     The histogram of raw p-value distribution will show if raw
     p-values are uniform in the  non significant range and therefore
     the BH correction can be applied.

_N_o_t_e:

     BH is the most used method for the correction of type I errors in
     microarray analysis. However, it has some limitation due to the
     initial hypotheses: The gene expressions are independent from each
     other. The raw distribution of p values should be uniform in the
     non significant range.
