_D_e_s_c_r_i_p_t_i_o_n:

     This function removes all probe sets in which a certain percentage
     of experiments is below a user defined intensity threshold.

_U_s_a_g_e:

     intensityFilter()

_D_e_t_a_i_l_s:

     The aim of non specific filtering is to remove the genes that are
     unlikely to carry information about the phenotypes under
     investigation. This filtering remove genes that do not have a
     centain level of, user defined, intensities in a set of, user
     defined, experiments.

_N_o_t_e:

     Factor analysis will be limited by the problem of having fewer
     samples than genes. Therefore, preselecting a smaller set of genes
     is definetively helpful.
