_P_l_o_t _D_e_n_s_i_t_i_e_s

_D_e_s_c_r_i_p_t_i_o_n:

     Plots the non-parametric density estimates using values contained
     in the columns of a matrix.

_U_s_a_g_e:

     plotDensity(mat, ylab = "density", xlab="x", type="l", col=1:6,...)

     plotDensity.AffyBatch(x, col = 1:6, log=TRUE,
     which=c("pm","mm","both"), ylab = "density", xlab = NULL, ...)

_A_r_g_u_m_e_n_t_s:

     mat: A matrix containing the values to make densities in the
          columns.

       x: A object of clase 'AffyBatch'

     log: logical value. If 'TRUE' the log of the intensities in the
          'AffyBatch' are plotted.

   which: should a histogram of the PMs, MMs, or both be made?

     col: The colors to use fot the different arrays

    ylab: a title for the y axis.

    xlab: a title for the x axis.

    type: type for the plot.

     ...: graphical parameters can be given as arguments to 'plot'
