_A_r_g_u_m_e_n_t_s:

       x: a LumiBatch object after lumiT transform, or a matrix or
          data.frame with VST parameter 

transFun: a character vector of transformation function (asinh or log2) 

plotRange: the plot range of untransformed data 

addLegend: add legend or not 

     ...: other parameter used by 'plot' function
