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

     A density plot of the non-spike-in expression with a rug of the
     average expression at each spike-in level.

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

     spkDensity(object, spkSlopeOut, cuts=TRUE, label = NULL, ...)

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

  object: a SpikeInExpressionSet object

spkSlopeOut: the output from the spkSlope function

    cuts: if TRUE vertical lines are drawn at the expression values
          separating low vs medium and medium vs high ALE strata

   label: a character string to insert into the plot title

     ...: arguments passed to the plot function

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

     This function requires the output of spkSlope.

_V_a_l_u_e:

     Density plot is produced.

_A_u_t_h_o_r(_s):

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

     data(affy)
     affySlope <- spkSlope(affy)
     spkDensity(affy,affySlope)
